[Intel-wired-lan] [PATCH v1 4/5] idpf: more info during virtchnl transaction time out

[Manoj Vishwanathan <manojvishy@google.com>]

Add more information related to the transaction like cookie, vc_op, salt
when transaction times out and include info like state, vc_op, chnl_opcode
when transaction salt does not match.

Sample output for transaction timeout:
-------------------
Transaction timed-out (op:5015 cookie:45fe vc_op:5015 salt:45 timeout:60000ms)
-------------------
