wifi: mt76: mt7925: skip reset work on hung bus

Browse Source 
Skip mt7925 reset handling once the bus is marked hung.

A hung bus cannot be recovered by issuing another device reset. Continuing
the reset path may only send more failing MCU or register accesses and
delay teardown. Return early from reset work and the USB reset path so the
failed device can be torn down quickly.
