[PATCH 3/5] doc: fix some ordered lists

[David Marchand <david.marchand@redhat.com>]

Ordered lists must start preceded by an empty line.
Entries must be separated by an empty line (as per our coding style).
Incorrectly indented lines are seen as a separator and result in
starting a new list in the rendered doc.

Fix issues in some guides.

Fixes: 85d9252e55f2 ("net/mlx5: add test for remote PD and CTX")
Fixes: 26b683b4f7d0 ("net/virtio: setup Rx queue interrupts")
Fixes: 9dcf5d15569b ("doc: clarify path selection in virtio guide")
Fixes: 68a03efeed65 ("doc: add Marvell cnxk platform guide")
Fixes: f6010c7655cc ("doc: add GSO programmer's guide")
Cc: stable@dpdk.org
