Commit 41d600274fbf ("extcon: int3496: process id-pin first so that we
start with the right status") starts the work on the workqueue before
registration to make sure we've a valid cable state directly after
registration.
But that commit moves the queuing of the work to before we even alloc the
extcon, causing a NULL pointer deref in the worker.
This commit moves the queuing of the work to after we alloc the extcon,
fixing the NULL pointer deref.
