The IPC sysctls implement the ctl_table_root::permissions hook and they
override the file access mode based on the CAP_CHECKPOINT_RESTORE
capability, which is being checked regardless of whether any access is
actually denied or not, so if an LSM denies the capability, an audit
record may be logged even when access is in fact granted.
It wouldn't be viable to restructure the sysctl permission logic to only
check the capability when the access would be actually denied if it's not
granted. Thus, do the same as in net_ctl_permissions() (net/sysctl_net.c)
- switch from ns_capable() to ns_capable_noaudit(), so that the check
never emits an audit record.
