ip*_mc_gsfget(): lift copyout of struct group_filter into callers
pass the userland pointer to the array in its tail, so that part gets copied out by our functions; copyout of everything else is done in the callers. Rationale: reuse for compat; the array is the same in native and compat, the layout of parts before it is different for compat. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
