Misc fixes and cleanup for project quota
1) The Coverity Scan reports some issues for the project quota patch, including: 1.1) zfs_prop_get_userquota() directly uses the const quota type value as the condition check by wrong. 1.2) dmu_objset_userquota_get_ids() may cause dnode::dn_newgid to be overwritten by dnode::dn->dn_oldprojid. 2) This patch fixes related issues. It also enhances the logic for zfs_project_item_alloc() to avoid buffer overflow. 3) Skip project quota ability check if does not change project quota related things (id or flag). Otherwise, it will cause chattr (for other non project quota flags) operation failed if project quota disabled.
