drm/i915: Use kcalloc more
No buffer overflows here, but better safe than sorry.
v2:
- Fixup the sizeof conversion, I've missed the pointer deref (Jani).
- Drop the redundant GFP_ZERO, kcalloc alreads memsets (Jani).
- Use kmalloc_array for the execbuf fastpath to avoid the memset
(Chris). I've opted to leave all other conversions as-is since they
aren't in a fastpath and dealing with cleared memory instead of
random garbage is just generally nicer.
