ath10k: Fix mutex unlock balance
ath10k_debug_read_target_stats is properly
protected by data_lock (spinlock). Remove
the unwanted mutex_unlock(&ar->conf_mutex)
[ BUG: bad unlock balance detected! ]
-------------------------------------
kworker/u4:0/12459 is trying to release lock
(&ar->conf_mutex) at:
[<c16a170d>] mutex_unlock+0xd/0x10
but there are no more locks to release!
Call Trace:
