dm raid: change rs_set_dev_and_array_sectors API and callers
Add a size argument to rs_set_dev_and_array_sectors as prerequisite
to fixing grown device resynchronization not occuring when new MD
bitmap pages have to be allocated as a result of the extension in
a follwup patch.
Also avoid code duplication by using rs_set_rdev_sectors
in the aforementioned function.
