[PATCH v4 13/23] qapi/schema: fix QAPISchemaArrayType.check's call to resolve_type

[John Snow]

Adjust the expression at the callsite to work around mypy's weak type
introspection that believes this expression can resolve to
QAPISourceInfo; it cannot.

(Fundamentally: self.info only resolves to false in a boolean expression
when it is None; therefore this expression may only ever produce
Optional[str]. mypy does not know that 'info', when it is a
QAPISourceInfo object, cannot ever be false.)
