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. Change-Id: I3956ef00c4f4a563155dc82ed8f95f097129fb0c CRs-Fixed: 2050134
