UBIFS: harmonize znode flag helpers
We have 3 znode flags: cow, obsolete, dirty. For the last flag we have a 'ubifs_zn_dirty()' helper function, but for the other 2 flags we use 'test_bit()' directly. This patch makes the situation more consistent and introduces helpers for the other 2 flags: 'ubifs_zn_cow()' and 'ubifs_zn_obsolete()'. Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com>
