nfp: bpf: round up the size of the stack
Kernel enforces the alignment of the bottom of the stack, NFP deals with positive offsets better so we should align the top of the stack. Round the stack size to NFP word size (4B). Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> Signed-off-by: Daniel Borkmann <daniel@iogearbox.net>
