drm/i915: Use memset64() to align the ring with MI_NOOP

Browse source

When filling the ring to align the emit pointer to the next cacheline,
use memset64() rather than open-coding it. As we know that we always
have an even number of dwords, we can replace the dword loop with the
qword equivalent.

v2: s/0/MI_NOOP<<32 | MI_NOOP/
