sky2: recovery deadlock fix

Prevent deadlock in sky2 recovery logic. sky2_down calls napi_synchronize
which gets stuck if napi was already disabled.

Fix by rearranging slightly and not calling napi_disable until after
both ports are stopped. The napi_disable probably is being overly
paranoid, but it is safe now.
