ext4: don't increase iversion counter for ea_inodes
commit 50f094a5580e6297bf10a807d16f0ee23fa576cf upstream.
ea_inodes are using i_version for storing part of the reference count so
we really need to leave it alone.
The problem can be reproduced by xfstest ext4/026 when iversion is
enabled. Fix it by not calling inode_inc_iversion() for EXT4_EA_INODE_FL
inodes in ext4_mark_iloc_dirty().
