staging: rtl8712: Improve suspend/resume functionality.
Cancel pending URBs during suspend operation to avoid receiving ESHUTDOWN
in read/write completion callbacks while the device is suspended.
Receiving ESHUTDOWN in read/write completion callbacks will cause the
driver to enter a non-functioning "stopped" state from which the driver is
unable to recover without reloading the module.
