A reorganisation of the PD allocation and deallocation in commit 9ba1377daa ("RDMA/ocrdma: Move PD resource management to driver.") introduced a double free on pd, as detected by static analysis by smatch: drivers/infiniband/hw/ocrdma/ocrdma_verbs.c:682 ocrdma_alloc_pd() error: double free of 'pd'^ The original call to ocrdma_mbx_dealloc_pd() (which does not kfree pd) was replaced with a call to _ocrdma_dealloc_pd() (which does kfree pd). The kfree following this call causes the double free, so just remove it to fix the problem. Fixes: 9ba1377daa ("RDMA/ocrdma: Move PD resource management to driver.")
