hw/block/nvme: add msix_qsize parameter
Decouple the requested maximum number of ioqpairs (param max_ioqpairs)
from the number of MSI-X interrupt vectors by introducing a new
msix_qsize parameter and initialize MSI-X with that. This allows
emulating a device that has fewer vectors than I/O queue pairs and also
allows more than 2048 queue pairs. To keep the device behaving as
previously, use a msix_qsize default of 65 (default max_ioqpairs + 1).
This decoupling was actually suggested by Maxim some time ago in a
slightly different context, so adding a Suggested-by.
