net: rfkill: Correct return value in invalid parameter case

Browse Source 
rfkill_set_hw_state_reason() does not return current combined
block state when its parameter @reason is invalid, that is
wrong according to its comments, fix it by correcting the
value returned.

Also reformat the WARN while at it.
