sys/linux/test: fix landlock_fs_ioctl
When running syz-manager with -mode run-tests --tests landlock_fs_ioctl -debug
we get this result:
#0 [1300ms] -> ioctl(0x4, 0x5460, 0x0)
#0 [1300ms] <- ioctl=0xffffffffffffffff errno=14
#0 [1300ms] -> ioctl(0x4, 0x5451, 0x0)
#0 [1300ms] <- ioctl=0x0
[...]
landlock_fs_ioctl none : FAIL: run 0: wrong call 5 result 14, want 13
The ioctl call returns EFAULT instead of EACCES.
Change this test to create a /dev/null device and use a valid device
IOCTL.
