Chengfeng Ye 1ac6cd87d8 ALSA: gus: fix null pointer dereference on pointer block ...

[ Upstream commit a0d21bb3279476c777434c40d969ea88ca64f9aa ]

The pointer block return from snd_gf1_dma_next_block could be
null, so there is a potential null pointer dereference issue.
Fix this by adding a null check before dereference.
