svc_rdma_op_ctxt's are pre-allocated and maintained on a per-xprt free list. This eliminates the overhead of calling kmalloc / kfree, both of which grab a globally shared lock that disables interrupts. To reduce contention further, separate the use of these objects in the Receive and Send paths in svcrdma. Subsequent patches will take advantage of this separation by allocating real resources which are then cached in these objects. The allocations are freed when the transport is torn down. I've renamed the structure so that static type checking can be used to ensure that uses of op_ctxt and recv_ctxt are not confused. As an additional clean up, structure fields are renamed to conform with kernel coding conventions. As a final clean up, helpers related to recv_ctxt are moved closer to the functions that use them.
