cmd/go/internal/vgo: speed up go.mod parsing

CL 106799 changed the mod file parser to be call
the fixer function for every module, version pair,
not just the ones with non-canonical semantic versions.
Of course, we don't want to hit the network for every line
of every go.mod, when most of them are fine.
Skip the network for the ones that are syntactically OK,
including proper matching between the module path and
major version.

For golang/go#24369.
