Subject: [PATCH] iser: Use local container_of definition
The code was implicitly dependent on container_of from
inifiniband/verbs.h, however that's been removed in rdma-core
latest release:
https://github.com/linux-rdma/rdma-core/commit/ce0274acffc78ed2861a56bdc34cdd3d60c20e1f
Define container_of locally if it's not already defined
(cherry picked from commit f1feb218e2823d236569f0ca3cfad07334f2a304)
