2ced60e9bf nvme: return number of completions processed
nvme_ctrlr_process_io_completions() and
nvme_ctrlr_process_admin_completions() now return the number of
completions processed.

This also adds the possibility of returning an error from the
process_*_completions functions (currently unused, but this at least
gets the API ready in case error conditions are added later).

81db062c52 nvme: fix wrong type of the deallocate function parameter
According to the specification, the dataset management for deallocate
attribute can support to 256 ranges, so we should use uint16_t
instead of uint8_t as the ranges parameter.

668847e150 nvme: add max completions limit to I/O polling
nvme_ctrlr_process_io_completions() now takes a second parameter,
max_completions, to let the user limit the number of I/Os completed on
each poll.

If there are many I/Os waiting to be completed, the
nvme_ctrlr_process_io_completions() function could run for a long time
before returning control to the user, so the max_completions parameter
lets the user have more control of latency.
