USB: gadget: f_mtp: dequeue request on error in mtp_read

In mtp_read(), if wait_event_interruptible() returns an error, we need to
remove the request from the EP queue.  Else, on the next call to mtp_read(), we
will attempt to enqueue the request again, potentially corrupting the
queue.  This is what happens with musb_gadget_queue(), which does not check for
duplicate requests.

Based on a similar change to f_adb.c
