cnss2: Collect firmware dump after SMMU fault happens

Currently, after enabling SMMU stage 1, SMMU driver will panic by
default if there is a SMMU fault. Config SMMU driver not to panic
for WLAN so that CNSS driver is able to collect firmware dump after
SMMU fault.

Fix misuse of error print API as well since they are in the same SMMU
function.
