description:
virtio: cosmetics - use (*pfn)(...) syntax.

Some people prefer to call function pointers without an explicit
dereference (that is purely cosmetic in this position), especially to
create faux c++ s->pfn(...) with function pointers in struct members.
Some prefer explicit dereference (that requires parens around it).

(pfn)(...) without dereference but with parens looks odd to both, so
make it conform to one of the established alternatives.

Same object code is generated.
