net: wireless: bcmdhd: Fixed a problem of buganizer issue (11190960)

	Problem : if PNO scan occurs in Driver after p2p scan,
		  we failed to do PNO scan
	Root cause : In the wl_run_escan function, we still goes into
	p2p scan code even though current scan is PNO which is kind of
	legacy scan.

	Solution : we need to clear the staus of P2P scan before doing
	PNO SCAN.

net-fixes: flow_dissector: prevent an infinite loop (CVE-2013-4348)

Jason Wang found that a malicious packet could make skb_flow_dissect()
loop forever. We must check that IP header has a valid ihl to avoid
this loop. It involves IPIP encapsulation and ihl = 0 to trigger.

Given this bug is critical, I cooked a patch before having
a fix in upstream kernel.

Tested:

 Compiled/booted
 Ran some tests on bnx2x and explicitely disabled hardware provided rxhash
 ethtool -K eth1 rxhash off
 ethtool -K eth2 rxhash off
