Why is this caller the only one in the file that gets distinguished
error messages? And why not use error_setg_errno() instead of
open-coding just one special errno value? If you're changing the return
value of fd_write_vmcore() anyways, I'd suggest that ALL callers in the
file be updated to use error_setg_errno().
