[PATCH -next, v2] selinux: correct the return value when loads initial sids

[Xiu Jianfeng]

It should not return 0 when SID 0 is assigned to isids.
This patch fixes it.

v2: remove the "out" label and return directly.

Fixes: e3e0b582c321a ("selinux: remove unused initial SIDs and improve handling")
