IB: Remove 'uobject->context' dependency in object destroy APIs
Now that we have the udata passed to all the ib_xxx object destroy APIs and the additional macro 'rdma_udata_to_drv_context' to get the ib_ucontext from ib_udata stored in uverbs_attr_bundle, we can finally start to remove the dependency of the drivers in the ib_xxx->uobject->context.
