ath11k: fix a locking bug in ath11k_mac_op_start()
This error path leads to a Smatch warning:
drivers/net/wireless/ath/ath11k/mac.c:4269 ath11k_mac_op_start()
error: double unlocked '&ar->conf_mutex' (orig line 4251)
We're not holding the lock when we do the "goto err;" so it leads to a
double unlock. The fix is to hold the lock for a little longer.
Fixes: c83c500b55b6 ("ath11k: enable idle power save mode")
