This switches to opencoding bio_add_pc_page, and thus losing the
max_hw_sectors check.  Additionally it exports a function that's
not used outside the file without a user showing up in the
series.

For now I'd suggest defeing this to the series that uses it, but
I suspect we can't really use common code between SG_IO and direct I/O
in the end due to the different nature of filesystem vs BLOCK_PC I/O.
