[RFC PATCH v2 05/14] hw/usb/redirect: Explicit we ignore few QEMUChrEvent in IOEventHandler

[Philippe Mathieu-Daudé]

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:

    CC      hw/usb/redirect.o
  hw/usb/redirect.c: In function ‘usbredir_chardev_event’:
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_BREAK’ not 
handled in switch [-Werror=switch]
   1361 |     switch (event) {
        |     ^~~~~~
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_MUX_IN’ not 
handled in switch [-Werror=switch]
  hw/usb/redirect.c:1361:5: error: enumeration value ‘CHR_EVENT_MUX_OUT’ not 
handled in switch [-Werror=switch]
  cc1: all warnings being treated as errors
