iwlwifi: remove command header flags field
The 'flags' field really has been reserved in the firmware API for a
very long time, probably since 4965. As a consequence, the field is
always 0 and checking for a IWL_CMD_FAILED_MSK flag makes no sense.
Rename the field to 'reserved', get rid of IWL_CMD_FAILED_MSK and
all the code for it.
