ext4: move the abort flag from s_mount_opts to s_mount_flags
We're running out of space in the mount options word, and
EXT4_MOUNT_ABORT isn't really a mount option, but a run-time flag. So
move it to become EXT4_MF_FS_ABORTED in s_mount_flags.
Also remove bogus ext2_fs.h / ext4.h simultaneous #include protection,
which can never happen.
