RDMA: Restore ability to fail on AH destroy
Like any other IB verbs objects, AH are refcounted by ib_core. The release of those objects are controlled by ib_core with promise that AH destroy can't fail. Being SW object for now, this change makes dealloc_ah() to behave like any other destroy IB flows. Fixes: d345691471b4 ("RDMA: Handle AH allocations by IB/core") Link: https://lore.kernel.org/r/20200907120921.476363-3-leon@kernel.org Signed-off-by: Leon Romanovsky <leonro@mellanox.com> Signed-off-by: Jason Gunthorpe <jgg@nvidia.com>
