TOMOYO: Fix quota and garbage collector.

Commit 059d84db "TOMOYO: Add socket operation restriction support" and
commit 731d37aa "TOMOYO: Allow domain transition without execve()." forgot to
update tomoyo_domain_quota_is_ok() and tomoyo_del_acl() which results in
incorrect quota counting and memory leak.
