RDMA/ocrdma: Make ocrdma_destroy_qp() easier to analyze

This patch does not change any functionality but avoids that sparse
reports the following:

drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:1818:31: warning: context imbalance in 'ocrdma_destroy_qp' - different lock contexts for basic block

Compile-tested only.
