[PATCH 2/5] selinux: use correct type for context length

[Christian Göttsche <cgzones@xxxxxxxxxxxxxx>]

security_sid_to_context() expects a pointer to an u32 as the address
where to store the length of the computed context.

Reported by sparse:

    security/selinux/xfrm.c:359:39: warning: incorrect type in argument 4 (different signedness)
    security/selinux/xfrm.c:359:39:    expected unsigned int [usertype] *scontext_len
    security/selinux/xfrm.c:359:39:    got int *
