Log: Fix bhyve's NVMe Completion Queue entry values The function which processes Admin commands was not returning the Command Specific value in Completion Queue Entry, Dword 0 (CDW0). This effects commands such as Set Features, Number of Queues which returns the number of queues supported by the device in CDW0. In this case, the host will only create 1 queue pair (Number of Queues is zero based). This also masked a bug in the queue counting logic.
