ALSA: compress_offload: fix remaining descriptor races in sound/core/compress_offload.c
3d3f43fab4cf ("ALSA: compress_offload: improve file descriptors
installation for dma-buf") fixed some of descriptor races in
snd_compr_task_new(), but there's a couple more left.
We need to grab the references to dmabuf before moving them into
descriptor table - trying to do that by descriptor afterwards might
end up getting a different object, with a dangling reference left in
task->{input,output}
