[PATCH 3/3] selinux: Use an other error code for an input validation failure in sidtab_insert()

[SF Markus Elfring]

The error code "-ENOMEM" was also returned so far when the parameter "s"
of this function contained a null pointer.
Now I find that the code "-EINVAL" is more appropriate in this case.
