milescovielloandClaude Opus 5.5 eb78c6a45f fix(libkernel): fail sceKernelStat with EFAULT for a null buffer ...

Crimson Desert (PPSA25286) calls sceKernelStat with a null buffer at
start-up, and main throws "sceKernelStat: sb is null", which ends the
title in its first second.

FreeBSD 11.4 looks the path up first and only then copies the result
out, so a null buffer gets EFAULT for a path that exists and the lookup
error for one that does not (sys/kern/vfs_syscalls.c, sys_stat):

	error = kern_statat(td, 0, AT_FDCWD, uap->path, UIO_USERSPACE,
	    &sb, NULL);
	if (error == 0)
		error = copyout(&sb, uap->ub, sizeof (sb));

sceKernelStat now does the same: the lookup and its errors are as
before, and a null buffer returns SCE_KERNEL_ERROR_EFAULT where the
status would be copied.
