Re: [PATCH] [BZ905179] audit: omit check for uid and gid validity in audit rules and data

audit rule additions containing "-F auid!=4294967295" were
failing with EINVAL.
UID_INVALID (and GID_INVALID) is actually a valid uid (gid) for setting and
testing against audit rules. Remove the check for invalid uid and gid when
parsing rules and data for logging.
Revert part of ca57ec0f00c3f139c41bf6b0a5b9bcc95bbb2ad7 (2012-09-11) to fix
this.
Eric, can you please take a look?

It concerns me that map_id_down() can return -1 on error and that this
change causes the kernel to no longer notice that error?
