Philipp Reisner 2deb8336d0 drbd: Fixed P_NEG_ACK processing for protocol A and B
Protocol A has no P_WRITE_ACKs, but has P_NEG_ACKs.
The master bio might already be completed, therefore the
request is no longer in the collision hash.
=> Do not try to validate block_id as request

In Protocol B we might already have got a P_RECV_ACK
but then get a P_NEG_ACK after wards.
