[PATCH v2 02/16] RDMA/ocrdma: Clarify the mm_head searching

[Jason Gunthorpe <jgg@nvidia.com>]

The intention of this code is to find matching entries exactly, the driver
never creates phys_addr's with different lens so the current expression is
not a bug, but it doesn't make sense and confuses review tooling.

Search for exact match instead.
