driver core: Fix error return code in really_probe()

Browse source 
In the case of error handling, the error code returned by the subfunction
should be propagated instead of 0.

Fixes: 1901fb2604 ("Driver core: fix "driver" symlink timing")
Fixes: 23b6904442 ("driver core: add dev_groups to all drivers")
Fixes: 8fd456ec0c ("driver core: Add state_synced sysfs file for devices that support it")
