tty: serial: Remove call to memset after pci_alloc_consistent

pci_alloc_consistent calls dma_alloc_coherent directly. In commit 518a2f1 ("dma-mapping: zero memory returned from dma_alloc_*"), dma_alloc_coherent has already zeroed the memory. So memset is not needed. Signed-off-by: Fuqian Huang <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Greg Kroah-Hartman <[email protected]>
