Subject: [PATCH] Coccinelle: zalloc_simple: Fix patch mode for dma_alloc_coherent()

Commit dfd32cad146e ("dma-mapping: remove dma_zalloc_coherent()"), in
removing dma_zalloc_coherent() treewide, inadvertently removed the patch
rule for dma_alloc_coherent(), leaving Coccinelle unable to auto-generate
patches for this case. Fix this.

Fixes: dfd32cad146e ("dma-mapping: remove dma_zalloc_coherent()")
