Chuck Tuffli d7e180feb7 bhyve: add locks around NVMe queue accesses 
The NVMe code attempted to ensure thread safety through a combination of
using atomics and a "busy" flag. But this approach leads to unavoidable
race conditions.

Fix is to use per-queue mutex locks to ensure thread safety within the
queue processing code. While in the neighborhood, move all the queue
initialization code to a common function.
