jiad 5b98663690 qcacld-3.0: Fix potential spinlock recursion on UP
wlan_hdd_update_txq_timestamp tries to grab txq spinlock
in __dev_queue_xmit context. Issue is txq spinlock is
already held before calling into driver's ndo_start_xmit
callback. On UP system, kernel throws a BUG and system
crashes.

Fix is to detect spinlock recursion and only tries
to grab the lock when it is not held on the same
CPU or not held.
