src/vfs/utils: Reset errno to zero when detect O_TMPFILE
For some filesystem that doesn't support O_TMPFILE, it will pass
ENOTSUP errno to upper layer. so it will report the following error:
QA output created by 696
vfstest.c: 1818: setgid_create_umask - Success - failure: is_setgid
vfstest.c: 2421: run_test - Operation not supported - failure...
To fix this, just reset errno before return.
