autofs: fix print format for ioctl warning message

All other warnings use "cmd(0x%08x)" and this is the only one with
"cmd(%d)".  (below comes from my userspace debug program, but not
automount daemon)

[ 1139.905676] autofs4:pid:1640:check_dev_ioctl_version: ioctl control interface version mismatch: kernel(1.0), user(0.0), cmd(-1072131215)
