wifi: iwlwifi: unify checks for HW error values
The hardware, depending on which part fails or times out,
returns 0xA5A5A5A. or 0x5A5A5A5. with the lowest 4 bits
encoding some further reason/status. However, mostly we
don't really need to care about the exact reasons, so
unify the checks for this to avoid hardcoding those magic
values all over the driver.
