ipv6: Re-arrange code in rt6_probe()
It is a prep work for the next patch to remove write_lock
from rt6_probe().
1. Reduce the number of if(neigh) check. From 4 to 1.
2. Bring the write_(un)lock() closer to the operations that the
lock is protecting.
Hopefully, the above make rt6_probe() more readable.
