qcacld-3.0: fix a potential spinlock lockup issue
When time stamping RX packets, spinlock
host_target_sync_lock will be hold if it's
now in TSF capturing state; if TSF-captured
IRQ happened at this moment, it will also
try to get host_target_sync_lock; if it's
handled on the same CPU, lockup will happen.
In the use-case, to update the current host
time, it's no need to get the spinlock in
this TSF-captured IRQ context, so move
host-time updating out of the lock.
