[ Upstream commit b5bfc21af5cb3d53f9cee0ef82eaa43762a90f81 ]
When we probe a SFP module, we expect to be able to call the upstream device's module_insert() function so that the upstream link can be configured. However, when the upstream device is delayed, we currently may end up probing the module before the upstream device is available, and lose the module_insert() call.
Avoid this by holding off probing the module until the SFP bus is properly connected to both the SFP socket driver and the upstream driver.
