cmd/go/internal/modload: don't query when fixing canonical versions

Browse Source 
If a canonical version is passed to fixVersion when loading the main
go.mod and that version don't match the module path's major version
suffix, don't call Query.

Query doesn't return a useful error in this case when the path is
malformed, for example, when it doens't have a dot in the first path
element. It's better to report the major version mismatch error.

Fixes #44494
