ext2: fix error msg when mounting fs with too-large blocksize 

When ext2 mounts a filesystem, it attempts to set the block device
blocksize with a call to sb_set_blocksize, which can fail for
several reasons.  The current failure message in ext2 prints:

  EXT2-fs (loop1): error: blocksize is too small

which is not correct in all cases.  This can be demonstrated
by creating a filesystem with

  # mkfs.ext2 -b 8192

on a 4k page system, and attempting to mount it.

Change the error message to a more generic:

  EXT2-fs (loop1): bad blocksize 8192

to match the error message in ext3.
