qcacld-3.0: move registration to end of driver load

An upcoming change will add synchronization to the driver load
operation. Effectively, driver load and psoc probe will need to be
exclusive operations. Because driver registration can synchronously
invoke psoc probe, move this registration to the end of the driver load
function. This prepares the way for adding synchronization around the
bulk of the load logic, and releasing it just before registration. This
avoids issues where driver load and psoc probe would otherwise execute
at the same time.
