cmd/doc: don't bother checking validity of symbols at top level

Browse Source 
No need to check as pieces further down do so anyway:

	%  go doc '&&.%$^'
	doc: symbol && is not a type in package fmt installed in "fmt"
	exit status 1
	%

Removing this check allows 'go doc sort.interface' or 'go doc
types.type' to discover sort.Interface and go/types.Type.

Easily

Fixes #34656.
