block/nvme: Correctly initialize Admin Queue Attributes
From the specification chapter 3.1.8 "AQA - Admin Queue Attributes"
the Admin Submission Queue Size field is a 0’s based value:
Admin Submission Queue Size (ASQS):
Defines the size of the Admin Submission Queue in entries.
Enabling a controller while this field is cleared to 00h
produces undefined results. The minimum size of the Admin
Submission Queue is two entries. The maximum size of the
Admin Submission Queue is 4096 entries.
This is a 0’s based value.
This bug has never been hit because the device initialization
uses a single command synchronously :)
