Subject: CVE-2016-6327 | Linux kernel crash in infiniband subsystem.

System using the infiniband support module ib_srpt were vulnerable to
a denial of service by system crash by a local attacker who is able to
abort writes to a device using this initiator.

There were multiple areas in which aborting a scsi command are able to
be handled, moving this to the correct location in the state machine
ensured that this condition was never triggered through this code

The null pointer situation was enabled via a non attacker controlled
meset() call, and this is not a use after free.  From my undestanding
it is a denial of service only.
