mmp: do not use O_DIRECT when working with regular file

Currently the mmp block is read using O_DIRECT to avoid any caching that
may be done by the VM. However when working with regular files this
creates alignment issues when the device of the host file system has
sector size larger than the blocksize of the file system in the file
we're working with.

This can be reproduced with t_mmp_fail test when run on the device with
4k sector size because the mke2fs fails when trying to read the mmp
block.

Fix it by disabling O_DIRECT when working with regular files. I don't
think there is any risk of doing so since the file system layer, unlike
shared block device, should guarantee cache consistency.

ridiculous sizes, such that the size of the resized block group
descriptor blocks exceed the original file system, and this would

   Illegal block number passed to ext2fs_test_block_bitmap #12440

   ./resize/resize2fs broken.img

Fortunately, aside from triggering these warning messages, the bug had
no other bad effects.

e2fsck: fix check of directories over 4GB

If directories grow larger than 4GB in size with the large_dir
feature, e2fsck will consider them to be corrupted and clear
the high bits of the size.

Since it isn't very common to have directories this large, and
unlike sparse files that don't have ill effects if the size is
too large, an too-large directory will have all of the sparse
blocks filled in by e2fsck, so huge directories should still
be viewed with suspicion.  Check for consistency between two of
the three among block count, inode size, and superblock large_dir
flag before deciding whether the directory inode should be fixed
or cleared, or if large_dir should be set in the superblock.

Update the f_recnect_bad test case to match new output.
