[PATCH] jbd copyout fix

When I converted journal_write_metadata_buffer() to kmap_atomic() I screwed
up the handling of the copyout buffers - we're currently writing four zeroes
into the user's page rather than into the data which is to be written to the
journal (oops).

Net effect: any block which starts with 0xC03B3998 gets scribbled on in
data=journal mode.
