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.
