Subject: [PATCH 12/21] e2fsck: check inline directory data "block" first

Since the inline data flag will cause the extent/block map iteration
code to abort fsck early, move the test for the inode flag and the
actual block check call further forward in check_blocks.  This
eliminates an e2fsck abort on an inline data symlink when the file ACL
block is set.
