Wifi: Fix for connection failure between third client and GC.

When third device sends a connection request to the group client, the
existing connection is terminating and also the ongoing connection not
successful.Currently as there is  no use case where third device is
connecting to GC,and the existing onnection getting terminated.This
is addressed by ignoring the new connection request from third client
to GC and the existing connection is intact.

wifi: Fix for connection between GO and p2p device

When GO sends an invitation request to the p2p device without
persistent profile, GO gets an invitation result=8 which means
unknown group, when GO receives invitation result 8, its tries
to remove persistent profile of the client but it will not be able
find the profile so it does continue with sending the invitation
so the connection fails. To address this, ignore if there are no
persistent profiles found for the client and continue with sending
the Invitation request to the client to make connection succesful
connection. As GO has single profile saved unlike client which
saves multiple profiles of GO.

p2p:Fix for discovery failure until STA is connected to AP.

The station when connecting to AP (wifi state is either
connecting or obtaining ip address) shall stop the already
issued p2p_find on the DHCP start and start the same after
the DHCP handshake. p2p service manager shall return a failure
for any p2p_find operation during these period resulting in a
discover failure.
Address this by deferring the p2p_find issued during this period
(set mDiscoveryPostponed to true) rather than returning a failure.

P2P: Fix for GO inviting a p2p device.

A p2p device on an invitation request from the peer invokes
p2p_peer command to know if the peer is a p2p device / GO.
Due to the cached entries there would be a possibility of
not getting the updated information, ending up in the wrong
negotiation with the invited peer. Thus do not rely on
p2p_peer command, rather assume that the peer is a GO on an
invitation request, provided there is no persistent network
configured.

Remove opaque check in preparing dirty region

Since preserve swap is enabled, we need to clear the color buffer
when the scissor rect is prepared for a new process. This prevents
garbage being present from the previous process in the color buffer.

Fix stencil buffer bug.

Stencil test is enabled by setStencilFromClip(), but not disabled
in some use case, which causes some of the pixels are discarded by
mistake in draws followed. Disable stencil test when there is no
