refactor: put nvme_cmd_wait directly in sqytdbl_write instead
...
This also fixes the strange crashing (I think... I have not been able to
replicate it) when creating the I/O queues, as I think what happens is
since I didn't wait for the I/O completion queue to be created, the CQID
may not be valid when creating the I/O submission queue which is why the
system weirded out like that.

perf: remove unneeded timeout code in controller reset/startup
...
Due to a misunderstanding, I thought the spec stated that you have to
wait for a specified duration after CSTS.RDY changes, but in reality
it's just the timeout value. I've included the timeout on debug builds
anyway just so you can see the messages it prints to the board without
dissapearing instantly.

Getting number of queues doesn't involve DPTR field in any way at all,
so no point in having it there.
