Subject: [PATCH v1 2/2] net: rfkill: Fix a logic error within rfkill_set_hw_state_reason()

Kernel API rfkill_set_hw_state_reason() wrongly gets previous block state
by using its parameter @reason as reason mask.

Fixed by using @reason_mask as reason mask.

Fixes: 14486c82612a ("rfkill: add a reason to the HW rfkill state")
