Subject: [PATCH 0/2] wifi: ath11k: fix ioremap() leak

smatch flagged the following issue:

drivers/net/wireless/ath/ath11k/ahb.c:1218 ath11k_ahb_probe() warn: 'ab->mem_ce' from ioremap() not released on lines: 1218.

Fix it by refactoring the ioremap and iounmap code and then calling the
unmap in the ath11k_ahb_probe() error path.
