This patch enables vector operation for bdev drivers aio, malloc and
nvme.
The rbd driver still handle only one vector.

Starting the subsystem consists of firing an event
to the subsystem poller's lcore and performing
I/O channel initialization (for virtual NVMe
subsystems) before starting the poller.
Previously the subsystem would be started immediately
when created, which was before the subsystem's
mode and other parameters (such as a virtual subsystem's
bdevs) have been set. This resulted in no I/O channels
being allocated in virtual subsystem mode.
So break out the start code into a new
nvmf_tgt_start_subsystem() function, which clients
must call after fully initializing a subsystem created
with nvmf_tgt_create_subsystem().

Extend the check added in commit
7552ee5512 ("nvmf_tgt: fail if NVMe
controller is not found") to the RPC interface.
Also remove the default PCI address from rpc.py, since it is not a
useful default - the user must specify a PCI address, which will vary
depending on the configuration of the machine.

The get_nvmf_subsystems RPC reported the PCI address of direct-mode
NVMe devices as individual integers, but the construct_nvmf_subsystem
call requires pci_address in a string format (%x:%x:%x.%x).
Change get_nvmf_subsystems to format the PCI address in the same way
that construct_nvmf_subsystem takes as a parameter for consistency.

This is required since pollers are now directly removed
(rather than scheduling an event) when the unregister call
is made on the poller's lcore.
Without this change, if a poller is registered then
immediately unregistered, the unregistration will seg
fault since the event adding the poller has not executed
yet.
Also add a test case that exhibits the sequence of events
described in this commit message.
