important bug fix and some micro optimizations
...
As for the fix, the submission queues weren't properly being zeroed out
due to a small typo. The other stuff has some commented out stuff that
I'm currently debugging and working on.

significant refactoring
...
* Removed useless `nvme_wait` call
* Remove phase tag bit check in favor of spinlock checking
* Added back in queue wrapping (though, it still needs work)
* Fix in `is_queue_full` which didn't pop bx off the stack when
returning in some circumstances

fix: nvme_readwrite and build_prp_list
...
This fixes the number of PRPs calculation before build_prp_list is
invoked. It also accounts for the fact that the NLB field in the NVMe
I/O read and write commands is a 0-based value, unlike numsectors.
start_sector is also converted into the appropriate LBA number as it
should be before sending the I/O command.

refactor: tweak some things
...
First of all, the driver will now abort initialization if it encounters
the first found namespace LBADS is not 512, since KolibriOS doesn't
support a LBADS greater than 512 as of now.
This commit also removes verbose debug logs and adds appropriate error
codes to nvme_readwrite
