[PATCH 2/2] drm/nouveau/abi16: fix handles past the 32nd one

[Ilia Mirkin]

abi16->handles is a u64, so make sure to use 1ULL << val when modifying.

Noticed this when doing the previous patch. I'm not sure whether this affects
64-bit builds or not, didn't care to look at the assembly or check the
standard.
