selinux: fix residual uses of current_security() for the SELinux blob
We need to use selinux_cred() to fetch the SELinux cred blob instead
of directly using current->security or current_security(). There
were a couple of lingering uses of current_security() in the SELinux code
that were apparently missed during the earlier conversions. IIUC, this
would only manifest as a bug if multiple security modules including
SELinux are enabled and SELinux is not first in the lsm order. After
this change, there appear to be no other users of current_security()
in-tree; perhaps we should remove it altogether.
Fixes: bbd3662a8348 ("Infrastructure management of the cred security blob")
