Subject: [PATCH] ext3: Return EIO if new block is allocated from system zone.

If the block allocator gets blocks out of system zone ext3 calls
ext3_error. But if the file system is mounted with errors=continue
return with -EIO.

System zone is the block range mapping block bitmap, inode bitmap and inode
table.
