Subject: quota: Make sure the limit return value is initialized when quota_get_resource()... 
X-Git-Tag: 2.2.19.rc1~15

quota: Make sure the limit return value is initialized when quota_get_resource() returns 0
Later on a debug log message in quota_over_flag_check_root() was accessing
the limit, which wasn't necessarily initialized.

Also initialized value return value just as well to be safe.
