iwlwifi: return commands with error on FW error
When a firmware error occurs, don't just abort synchronous
commands but also return an error (-EIO) and block any new
commands as well. Currently, an error is only returned if
WANT_SKB was set which is confusing and can lead to issues.
Blocking is done until a new firmware image is loaded.
