Björn Töpel e2ce367488 xsk: simplify AF_XDP socket teardown ... Prior this commit, when the struct socket object was being released, the UMEM did not have its reference count decreased. Instead, this was done in the struct sock sk_destruct function. There is no reason to keep the UMEM reference around when the socket is being orphaned, so in this patch the xdp_put_mem is called in the xsk_release function. This results in that the xsk_destruct function can be removed! Note that, it still holds that a struct xsk_sock reference might still linger in the XSKMAP after the UMEM is released, e.g. if a user does not clear the XSKMAP prior to closing the process. This sock will be in a "released" zombie like state, until the XSKMAP is removed.
