USB: gadget: f_mtp: Fix problems transferring files from device to host

Exit from send_file_work immediately when a cancel request is received.

Only busy status if there is a cancel pending that has not been repoorted to userspace.
This avoids a race condition that can occur when mtp_read resets the state
to STATE_BUSY before we report status OK back to the host.
