Subject: [PATCH v2] wifi: rfkill: Correct parameter type for
 rfkill_set_hw_state_reason()

From: Zijun Hu <quic_zijuhu@...cinc.com>

Change type of parameter @reason to enum rfkill_hard_block_reasons
for API rfkill_set_hw_state_reason() according to its comments, and
all kernel callers have invoked the API with enum type actually.
