Currently, virtio_find_vqs() and virtio_find_vqs_ctx() accept array of
names, callbacks and ctx (in case of the second one) as separate args.
That became inconvenient as the ctx addition showed.
For virtio_net control queue, an indication of queue flavour (slow path)
is going to be needed to be passed to PCI transport in order to
assign vectors properly, another array added to virtio_find_vqs_ctx()
arg list would not be nice and convenient.
Instead, introduce a structure to carry vq callback, name and ctx. Pass
array of these structures to virtio_find_vqs() and all the way down to
transport find_vqs() op implementation.
That allows to easily extend what needs to be passed down. Also, it
makes the code a bit more cleaner. We get rid of separate
virtio_find_vqs_ctx() helper.
This patchset does the conversion in steps, using temporary _info() op
and helper. Note they are renamed back.
Patch #1 does one forgotten conversion to virtio_find_single_vq().
Patches #2 and #3 do preparations for find_vqs_info() op introduction.
Patch #4 introduces new op find_vqs_info() to replace find_vqs() it also
introduces struct virtio_queue_info and virtio_find_vqs_info() helper.
Patches #5 and #6 convert transports to implement find_vqs_info() op
that accepts array of virtio_queue_info structs.
Patch #7 converts virtio_find_single_vq() to use the new way as well.
Patch #8 removes original find_vqs() op.
Patch #9 renames find_vqs_info() to find_vqs() and completes first part
of conversion this patches does.
Patches #10-#17 convert virtio_find_vqs() and virtio_find_vqs_ctx()
users to use new virtio_find_vqs_info() helper.
Patch #18 removes no longer used virtio_find_vqs() and
virtio_find_vqs_ctx() helpers.
Patch #19 finalizes the conversion by renaming virtio_find_vqs_info()
to virtio_find_vqs().
