dm: remove unused 'num_write_bios' target interface
No DM target provides num_write_bios and none has since dm-cache's
brief use in 2013.
Having the possibility of num_write_bios > 1 complicates bio
allocation. So remove the interface and assume there is only one bio
needed.
If a target ever needs more, it must provide a suitable bioset and
allocate itself based on its particular needs.
