Commit Message

Rebecca Troy July 1, 2022, 8:57 a.m. UTC 
  Currently when running the dpdk-perf-test with docsis
security sessions, a segmentation fault occurs. This
is due to the check being made that the session is not
equal to op->sym->sec_session. This check passes the
first time but on the second iteration fails and doesn't
create the build_request.

This commit fixes that error by getting the ctx first
from the private session data and then comparing ctx,
rather than op->sym->sec_session, with the sess.

Fixes: fb3b9f492205 ("crypto/qat: rework burst data path")

Fix formatting of above if check.
