selinux: Use current_security() when possible
There were a number of places using the following code pattern: struct cred *cred = current_cred(); struct task_security_struct *tsec = cred->security; ... which were simplified to the following: struct task_security_struct *tsec = current_security(); Signed-off-by: Paul Moore <paul.moore@hp.com> Acked-by: Eric Paris <eparis@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
