[PATCH 6.0 283/862] wifi: mt76: mt7615: add mt7615_mutex_acquire/release in mt7615_sta_set_decap_offload
From: Greg Kroah-Hartman

[ Upstream commit 765c69d477a44c088e5d19e7758dfa4db418e3ba ]
Similar to mt7921 driver, introduce mt7615_mutex_acquire/release in
mt7615_sta_set_decap_offload in order to avoid sending mcu commands
while the device is in low-power state.
Fixes: d4b98c63d7a77 ("mt76: mt7615: add support for rx decapsulation offload")
