From: Jan Kara <jack@suse.cz>
commit 9db176bceb5c5df4990486709da386edadc6bd1d upstream.
When CONFIG_QFMT_V2 is configured as a module, the test in ext4_feature_set_ok() fails and so mount of filesystems with quota or project features fails. Fix the test to use IS_ENABLED macro which works properly even for modules.
