e2fsck: declare the size of bh->b_data to be 4096 in jfs_user.h
When allocating buffer_heads in e2fsck and debugfs the actual size of
the memory which is requested is based on the file system block size.
So the actual size of b_data in struct buffer_head doesn't actually
matter, except that it can triggers a UBSAN error when running the
e2fsck regression test. So change it to be 4096 to avoid this false
positive.
