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)
