target: Remove error messages as no .get_gdb_fileio_info

If target does not support semi-hosting function, it has
no need to provide .get_gdb_fileio_info callback. OpenOCD
will use default function target_get_gdb_fileio_info_default.
The default function just return ERROR_FAIL and gdb_server
will treat every halted condition as normal halted and
return "Txx" to gdb.
