wifi: mt76: mt7925: fix a potential association failure upon resuming

In multi-channel scenarios, the granted channel must be aborted before
suspending. Otherwise, the firmware will be put into a wrong state,
resulting in an association failure after resuming.

With this patch, the granted channel will be aborted before suspending
if necessary.
