bus: mhi: core: Drop the references to mhi_dev in mhi_destroy_device()

For some scenarios like controller suspend and resume, mhi_destroy_device()
will get called without mhi_unregister_controller(). In that case, the
references to the mhi_dev created for the channels will not be dropped
but the channels will be destroyed as per the spec. This will cause issue
during resume as the channels will not be created due to the fact that
mhi_dev is not NULL.

Hence, this change decrements the refcount for mhi_dev in
mhi_destroy_device() for concerned channels and also sets mhi_dev to NULL
in release_device().
