ext4: do not set extents feature from the kernel
We've talked for a while about getting rid of any feature- setting from the kernel; this gets rid of the code which would set the INCOMPAT_EXTENTS flag on the first file write when mounted as ext4[dev]. With this patch, if the extents feature is not already set on disk, then mounting as ext4 will fall back to noextents with a warning, and if -o extents is explicitly requested, the mount will fail, also with warning.
