RDMA/uverbs: Initialize udata struct on destroy flows
Cited commit introduced the udata parameter to different destroy flows but the uapi method definition does not have udata (i.e has_udata flag is not set). As a result, an uninitialized udata struct is being passed down to the driver callbacks. Fix that by clearing the driver udata even in cases where has_udata flag is not set. Fixes: c4367a26357b ("IB: Pass uverbs_attr_bundle down ib_x destroy path") Cc: Shamir Rabinovitch <shamir.rabinovitch@oracle.com> Co-developed-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Jason Gunthorpe <jgg@ziepe.ca> Signed-off-by: Gal Pressman <galpress@amazon.com> Signed-off-by: Jason Gunthorpe <jgg@mellanox.com>
