Fix DiscoveryFlowHandler when discovery_function returns bool

[kgraefe]

Proposed change

self._discovery_function is of type Callable[[HomeAssistant], Awaitable[bool] | bool]. Therefore it may or may not be a coroutine. The second case is not handled since commit #113115 which breaks the installation of the iOS component (#124461).

Fixes #124461 introduced by #113115
