yuan linyu 9b430b0863 usb: f_mass_storage: forbid async queue when shutdown happen 
commit b2d2d7ea0dd09802cf5a0545bf54d8ad8987d20c upstream.

When write UDC to empty and unbind gadget driver from gadget device, it is
possible that there are many queue failures for mass storage function.

The root cause is mass storage main thread alaways try to queue request to
receive a command from host if running flag is on, on platform like dwc3,
if pull down called, it will not queue request again and return
-ESHUTDOWN, but it not affect running flag of mass storage function.

Check return code from mass storage function and clear running flag if it
is -ESHUTDOWN, also indicate start in/out transfer failure to break loops.
