migration: Rework migrate_send_rp_req_pages() function
We duplicated the logic of maintaining the last_rb variable at both callers of
this function. Pass *rb pointer into the function so that we can avoid
duplicating the logic. Also, when we have the rb pointer, it's also easier to
remove the original 2nd & 4th parameters, because both of them (name of the
ramblock when needed, or the page size) can be fetched from the ramblock
pointer too.
