[PATCH v3 14/24] media: ngene: Remove call to memset after pci_alloc_consistent

[Fuqian Huang]

pci_alloc_consistent calls dma_alloc_coherent directly.
In commit 518a2f1925c3
("dma-mapping: zero memory returned from dma_alloc_*"),
dma_alloc_coherent has already zeroed the memory.
So memset is not needed.
