In the rds_iw_mr_pool struct the free_pinned field keeps track of memory pinned by free MRs. While this field is incremented properly upon allocation, it is never decremented upon unmapping. This would cause the rds_rdma module to crash the kernel upon unloading, by triggering the BUG_ON in the rds_iw_destroy_mr_pool function. This change keeps track of the MRs that become unpinned, so that free_pinned can be decremented appropriately.
