Takashi Iwai ca1362fdcb ALSA: memalloc: Catch call with NULL snd_dma_buffer pointer 
[ Upstream commit dce9446192 ]

Although we've covered all calls with NULL dma buffer pointer, so far,
there may be still some else in the wild.  For catching such a case
more easily, add a WARN_ON_ONCE() in snd_dma_get_ops().

Fixes: 37af81c599 ("ALSA: core: Abstract memory alloc helpers")
