btrfs: move btrfs_bio allocation to volumes.c
volumes.c is the place that implements the storage layer using the
btrfs_bio structure, so move the bio_set and allocation helpers there
as well.
To make up for the new initialization boilerplate, merge the two
init/exit helpers in extent_io.c into a single one.
