usb: gadget: f_mass_storage: Add schedule() in sleep_thread()

In case "ums" command is used on platforms which don't implement
g_dnl_board_usb_cable_connected() and USB cable is not connected,
we stay inside sleep_thread() forever and watchdog is triggered.

Add schedule() call to avoid this issue.
