Fix lockup on Sony ILCE-7M4 due to ptp_sony_9280

The ptp_sony_9280 command cause the ILCE-7M4 PTP interface to
immediately lock up upon receiving the command when in MTP mode.

Capture mode does not advertise 9280/9281 as supported and is not
impacted.  Camera storage is not accessible in capture mode.
