dblink: Avoid locking relation before privilege check.

The present coding of dblink's get_rel_from_relname() predates the
introduction of RangeVarGetRelidExtended(), which provides a way to
check permissions before locking the relation.  This commit adjusts
get_rel_from_relname() to use that function.
