LSM: restore certain default error codes
While in most cases commit b1d9e6b0 ("LSM: Switch to lists of hooks") retained previous error returns, in three cases it altered them without any explanation in the commit message. Restore all of them - in the security_old_inode_init_security() case this led to reiserfs using uninitialized data, sooner or later crashing the system (the only other user of this function - ocfs2 - was unaffected afaict, since it passes pre-initialized structures).
