[PATCH v2] dmaengine: idxd: Remove redundant memset() for eventlog allocation

From: Rajeshwar R Shinde <coolrrsh@gmail.com>

dma_alloc_coherent function already zeroes the array 'addr'.
So, memset function call is not needed.

This fixes warning such as:
drivers/dma/idxd/device.c:783:8-26:
WARNING: dma_alloc_coherent used in addr already zeroes out memory,
so memset is not needed.
