[PATCH v3 4/9] block: export bio_chain_and_submit

[zhangshida]

From: Shida Zhang <zhangshida@xxxxxxxxxx>

Export the bio_chain_and_submit function to make it available as a
common utility. This will allow replacing repetitive bio chaining
patterns found in multiple locations throughout the codebase.
