fs/ext2: remove ext2 revision 0 support

Browse Source 
Revision 0 is very old and misses a number of features.  From man mkfs.ext2:

Set  the  file system revision for the new file system.  Note that 1.2
kernels only support revision 0 file systems.  The default is to create
revision 1 file systems.

We are unlikely to have a lot of Linux 1.2.x users, so drop support for it.

As revision 1 is the default, drop the -E revision argument to mkfs.ext2 for
simplicity.
