Juhyung Park 786bcb1109 FROMGIT: f2fs: quota: fix loop condition at f2fs_quota_sync() 
cnt should be passed to sb_has_quota_active() instead of type to check
active quota properly.

Moreover, when the type is -1, the compiler with enough inline knowledge
can discard sb_has_quota_active() check altogether, causing a NULL pointer
dereference at the following inode_lock(dqopt->files[cnt]):
