a0a41eefb1 nvmf: allow inactive namespaces in virtual mode
Now that virtual mode namespaces can be chosen arbitrarily, there can be
holes in the ns_list.  Make sure all of the virtual mode code paths are
prepared to handle these inactive but valid NSIDs.

aff7e226f7 bdev: spdk_bdev_[read|write|flush|unmap|reset] now return int
It is not actually useful to be immediately returned
a handle to the bdev_io. There isn't anything valid
that the user can do with it at that point. Instead,
return an integer error code.

0801877b7d nvmf,direct: add AER support in direct mode.
After checking the code, aerl in our session is 0,
so there will be only 1 AER. So currently,
we will only handle 1 AER case.

When the AER event is triggered by real NVMe device owned
by the subsystem, it notifies all sessions belonging to
the subsystem.
