Subject: [PATCH 5.7 081/120] RDMA/core: Free DIM memory in error unwind

From: Leon Romanovsky <leonro@...lanox.com>

[ Upstream commit fb448ce87a4a9482b084e67faf804aec79ed9b43 ]

The memory allocated for the DIM wasn't freed in in error unwind path, fix
it by calling to rdma_dim_destroy().

Fixes: da6629793aa6 ("RDMA/core: Provide RDMA DIM support for ULPs")
