block: add a bio_list_merge_init helper

This is a simple combination of bio_list_merge + bio_list_init
similar to list_splice_init.  While it only saves a single
line in a callers, it makes the move all bios from one list to
another and reinitialize the original pattern a lot more obvious
in the callers.
