Simplify init_audio_filters() arguments

Remove the following arguments as redundant: in_channels, in_format,
out_minsize, out_maxsize. The first two always equal fields of the
sh_audio_t struct given as the first argument to the function. The
last two are unused after the allocation of sh_audio->a_out_buffer
was changed to be done on demand.

After the out_minsize and out_maxsize arguments are removed the
function preinit_audio_filters() is identical to init_audio_filters(),
so remove it and use the latter instead.
