dma-mapping: reject GFP_COMP for noncoherent allocations

dma-mapping: reject GFP_COMP for noncoherent allocations

While not quite as bogus as for the dma-coherent allocations that were
fixed earlier, GFP_COMP for these allocations has no benefits for
the dma-direct case, and can't be supported at all by dma dma-iommu
backend which splits up allocations into smaller orders.  Due to an
oversight in ffcb75458460 that flag stopped being cleared for all
dma allocations, but only got rejected for coherent ones, so fix up
these callers to not allow __GFP_COMP as well after the sound code
has been fixed to not ask for it.

Fixes: ffcb75458460 ("dma-mapping: reject __GFP_COMP in dma_alloc_attrs")
