chrg6 61b8a6d62c Wait for room in the flight table in mem_lazy_skip only when there is another buffer's range to give back. ...

The review found that memory.c mem_lazy_skip's loop over the ranges armed for another buffer waited for a free entry
in the flight table before it looked for one. On its last pass, which finds nothing left to take, the replay could
still wait for another thread's fetch to end when the table was full. Now it looks first, and waits for room only when
it has a range to take and every entry is in use, then looks again. The search is lazy_foreign_locked, shared with the
check before the loop. Not reproduced before the change; lazy_fetch_check passed in all its scenarios (foreign and
flood among them).
