Bluetooth: Handle closing of UHID Poll thread from btif context

This patch handles closing of uhid driver from btif context instead of
bta context. since now uhid close would be handled in btif context, bta
thread would be unblocked for handling avdtp media packets.
Wihtout this change bta thread was getting blocked upto
max 500 ms when HID is disconnected, which caused delay in sending
of AVDTP Media packets during A2DP and HID concurrent test cases resulting
in audio break on BT headset dueing HID disconnection.

Bluetooth: fix sniff issue with multiple rfcomm connection in same ACL.

When there are multiple rfcomm connection with same appid and peer bd
address, we were clearing jv pm control block in addition to closing
connection to service with registered app id. Since appid is common
across all the client and server app registed to jv. we were clearing
entire connection to service for this appid and peer bdadres which was
corrupting sniff logic, when another rfcomm connection exists with same
peer bdaddress. So avoiding closing of connection to the service when
multiple rfcomm connection exists in same ACL.

Bluetooth: Avoid premption while modifying gki timer queue

Addition/Removal of timer nodes to the timer_queue happening
without protection,
When both Addition/removal happens concurrently there could
be a chance that remove timer might have deleted the node
and the same might be getting accessed in add timer while
adding the timer node to the list, this could lead exception.

Added changes to synchronize both addition and removal
of timer nodes from timer queue, so that addition/removal
happens sequentially.
