Since the io_channel will be passed to the underlying bdev's
read/write/... functions later, we need to also acquire an io_channel
for the underlying bdev, not for the virtual bdev.

The PCIe transport initializes the quirks directly, so the generic hook
to get PCI ID is no longer necessary. This path was dead code.

The logic to fail queue pairs when the controller is failed should be
handled in the generic code, not in the individual transports.
This also allows nvme_qpair_fail() to be private to nvme_qpair.c.

When we do frequent same subsystem add/delete,
we will face the adding issue. For example,
1 Add subsystem A
2 Delete subsystem A
3 Add subsystem A (Fail in this step).
The reason is that we did not correctly free
the listener resources of subsystems, and this patch
can solve this issue.

The $(ENV_LIBS) variable was including system library linker arguments
like '-ldl', but $(ENV_LIBS) is intended to be used as a dependency for
other Makefile targets, and those arguments don't belong there.
Add the system library linker arguments to ENV_LINKER_ARGS instead.

In our previous code, we did not ack the event in
exceptional cases when we get a event via rdma_get_cm_event.
Thus, the code may block with in this statement:
rdma_destroy_id(rqpair->cm_id);
in some exceptiaonal cases. And this patch will solve this
issue.
