scd: Fix suspend/resume handling for CCID driver.
* scd/ccid-driver.c (intr_cb): Try submitting INTERRUPT urb
to see if it's suspend/resume.
--
Upon suspend/resume, LIBUSB_TRANSFER_NO_DEVICE is returned, since all
URBs are cancelled. We need to see if it's real NODEV error or its by
suspend/resume. We can distinguish by sending URB again.
