ccid: Fix dwProtocols advertisement of T=0

Commit d7d218ef02d87c637d20d64da8f575d434ff6f78 attempted to change
dwProtocols to only advertise support for T=0 and not T=1.  The change
was incorrect as it changed 0x00000003 to 0x00010000.

lsusb -v in a linux guest shows:
"dwProtocols         65536  (Invalid values detected)", though the
smart card could still be accessed.  Windows 7 does not detect inserted
smart cards and logs the the following Error in the Event Logs:

    Source: Smart Card Service
    Event ID: 610
    Smart Card Reader 'QEMU QEMU USB CCID 0' rejected IOCTL SET_PROTOCOL:
    Incorrect function. If this error persists, your smart card or reader
    may not be functioning correctly

    Command Header: 03 00 00 00

Setting to 0x00000001 fixes the Windows issue.
