ALSA: hda/ca0132: minor fix for allocation size

Browse Source 
[ Upstream commit 3ee0fe7fa39b14d1cea455b7041f2df933bd97d2 ]

Although the "dma_chan" pointer occupies more or equal space compared
to "*dma_chan", the allocation size should use the size of variable
itself.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
