libceph: isolate kmap() call in write_partial_msg_pages()
In write_partial_msg_pages(), every case now does an identical call
to kmap(page). Instead, just call it once inside the CRC-computing
block where it's needed. Move the definition of kaddr inside that
block, and make it a (char *) to ensure portable pointer arithmetic.
We still don't kunmap() it until after the sendpage() call, in case
that also ends up needing to use the mapping.
