The capability check should not be audited since it is only being used
to determine the inode permissions. A failed check does not indicate a
violation of security policy but, when an LSM is enabled, a denial audit
message was being generated.
The denial audit message can either lead to the capability being
unnecessarily allowed in a security policy, or being silenced potentially
masking a legitimate capability check at a later point in time.
Similar to commit d6169b0206 ("net: Use ns_capable_noaudit() when
determining net sysctl permissions")
Fixes: 7863dcc72d ("pid: allow pid_max to be set per pid namespace")
