This is achieved by rewriting some inline assembly and changing
ProcessorID to be 32 bit value. For some reason if processor id
is 8 bits gcc runs out of 8 bit registers on i386.

Kernel: Cleanup NVMe Queue command submission
...
There is techically a race condition on thread sleep and checking
done mask. This patch allows read to success even if this race
condition is hit, although the full timeout has to be waited.
This can be fixed in future with some sort of wait queues that
can properly handle this race condition.

Scheduler now has its own data SchedulerQueue which holds active nad
blocking thread lists. This removes need for BAN/Errors.h and making
current thread separate element instead of iterator into linked list.
This makes it possible to have current_thread on each processor
instead of a global one in Scheduler.
