[PATCH v2] security: fix description of values returned by cap_inode_need_killpriv

[stefanb@linux.vnet.ibm.com (Stefan Berger)]

cap_inode_need_killpriv returns 1 if security.capability exists and
has a value and inode_killpriv() is required, 0 otherwise. Fix the
description of the return value to reflect this.
