Wang Weiyang 697e55b941 device_cgroup: Roll back to original exceptions after copy failure
commit e68bfbd3b3c3a0ec3cf8c230996ad8cabe90322f upstream.

When add the 'a *:* rwm' entry to devcgroup A's whitelist, at first A's
exceptions will be cleaned and A's behavior is changed to
DEVCG_DEFAULT_ALLOW. Then parent's exceptions will be copyed to A's
whitelist. If copy failure occurs, just return leaving A to grant
permissions to all devices. And A may grant more permissions than
parent.

Backup A's whitelist and recover original exceptions after copy
failure.
