Previously, there was bio_clone() but it only allocated from the fs bio

This changes bio_clone() to become bio_clone_bioset(), and then we add
bio_clone() and bio_clone_kmalloc() as wrappers around it, making use of
the functionality the last patch adedd.

This will also help in a later patch changing how bio cloning works.

I'd prefer simply adding @bioset to bio_clone() so that the caller
always has to make the choice consciously.  We're updating all the
callers anyway.

Thanks.
