mt76: Fix queue ID variable types after mcu queue split

Clang warns in both mt7615 and mt7915:

drivers/net/wireless/mediatek/mt76/mt7915/mcu.c:271:9: warning: implicit
conversion from enumeration type 'enum mt76_mcuq_id' to different

Use the proper type for the queue ID variables to fix these warnings.
Additionally, rename the txq variable in mt7915_mcu_send_message to be
more neutral like mt7615_mcu_send_message.
