staging: rtl8712: Improve suspend/resume functionality.
Fix a driver hang caused by earlier suspend/resume cycles. By handling a
ENODEV error during suspend as a real error we eventually end up stopping
the whole driver.
Fix this by handling the ENODEV error (during suspend) essentially by
retrying.
