Using kfifos for ID management was limiting the number of QPs and
preventing NP384 MPI jobs. So replace it with a simple bitmap
allocator.
Remove IDs from the IDR tables before deallocating them. This bug was
causing the BUG_ON() in insert_handle() to fire because the ID was
getting reused before being removed from the IDR table.
