rocker: fix possible null pointer dereference in rocker_router_fib_event_work
Currently, rocker user may experience following null pointer
derefence bug:
[ 3.062141] BUG: unable to handle kernel NULL pointer dereference at 00000000000000d0
[ 3.065163] IP: rocker_router_fib_event_work+0x36/0x110 [rocker]
The problem is uninitialized rocker->wops pointer that is initialized
only with the first initialized port. So move the port initialization
before registering the fib events.
Fixes: 936bd486564a ("rocker: use FIB notifications instead of switchdev calls")
