[PATCH 21.11] vhost: fix doxygen warnings

[Kevin Traynor <ktraynor@redhat.com>]

Doxygen 1.9.5 gives a false positive warnings [1]
for @params on function pointer params.

This is fixed in doxygen 1.9.6 but Fedora 37 uses
1.9.5 at present.

Remove the @param but keep the comments for info in
the header file as a workaround until 1.9.6 is more
widely deployed.
