[PATCH v2 2/2] gpudev: use page_size in comm_list creation

[eagostini]

From: Elena Agostini <eagost...@nvidia.com>

Memory allocated for CPU mapping the status flag
in the communication list should be aligned to the
GPU page size.

Fixes: 9b8cae4d991e ("gpudev: use CPU mapping in communication list")
