wifi: mt76: mt7615: add mt7615_mutex_acquire/release in mt7615_sta_set_decap_offload
[ 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.
