ccid-card-passthru: Explicit we ignore QEMUChrEvent in IOEventHandler

Browse source 
The Chardev events are listed in the QEMUChrEvent enum. To be
able to use this enum in the IOEventHandler typedef, we need to
explicit all the events ignored by this frontend, to silent the
following GCC warning:

  hw/usb/ccid-card-passthru.c: In function ‘ccid_card_vscard_event’:
  hw/usb/ccid-card-passthru.c:314:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not handled in switch [-Werror=switch]
    314 |     switch (event) {
        |     ^~~~~~
  hw/usb/ccid-card-passthru.c:314:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ not handled in switch [-Werror=switch]
  hw/usb/ccid-card-passthru.c:314:5: error: enumeration value ‘CHR_EVENT_CLOSED’ not handled in switch [-Werror=switch]
  cc1: all warnings being treated as errors
