Wey-Yi Guy 7acc7c683a iwlwifi: do not perferm force reset while doing scan
When uCode error condition detected, driver try to perform either
rf reset or firmware reload in order bring device back to
working condition.

If rf reset is required and scan is in process, there is no need
to issue rf reset since scan already reset the rf.

If firmware reload is required and scan is in process, skip the
reload request. There is a possibility firmware reload during
scan cause problem.
