USB: f_mtp: Fix corner cases in MTP driver while syncing
Currently if USB composition switch happens while file transfer is
happening either from/to device, ep_queue fails and sets device state
to ERROR even if device state is already set to OFFLINE in function
disable call.
As part of ioctl call, if the state is not offline, moving the device
state to READY and returning the error. Since the device state is marked
as READY, the next write call tries to queue the request to hardware and
is blocked and due to this, userspace is not calling the release function.
Hence next mtp open fails even after cable reconnection.
