With the old code, when you allocate a bio from a bio pool you have to
implement your own destructor that knows how to find the bio pool the
bio was originally allocated from.

This adds a new field to struct bio (bi_pool) and changes
bio_alloc_bioset() to use it. This makes various bio destructors
unnecessary, so they're then deleted.

Please add Cc: to maintainers of each modified subsystem.  Other than
that, nice cleanup even without the later removal of bi_destructor.

Thanks.
