remap: fix check when to apply specialized code path

Browse source 
the specialized code path just duplicate samples, so are only
applicable if the volume in map_table is == 1.0 (or == 0x10000);
don't use them for volumes >= 1.0

compare the integer version of the volume stored in map_table;
comparing floats is ugly (als leads to compiler warnings)
