[PATCH 5/5] Add dummy return 0 to Xnest & Xephyr io error handler for Sun compilers

[Alan Coopersmith]

Required in order to build with Studio cc now that xorg-macros is
setting -errwarn=E_FUNC_HAS_NO_RETURN_STMT since it doesn't
recognize that the noreturn attribute makes it pointless.

Otherwise compiler exits with errors:
"Display.c", line 65: Function has no return statement : x_io_error_handler
"hostx.c", line 341: Function has no return statement : x_io_error_handler
