usrp2: got fw working on usrp2+nseries (crosses fingers)

The abort issue seemed to be cause by the listeners table not being initialized.
Also gave the pic handler the initialization works to be consistent but not needed as it was static initialized.
And finally, doubly set the packet router handshake ctrl before entering the claim calls (seemed to fix the lockup, perhaps a bad init state?)
