[sheepdog-users] [PATCH stable-0.7] object cache: fix a wrong conversion assignment

[Hitoshi Mitake]

From: Liu Yuan <namei.unix at gmail.com>

If we assign the integer to a wider one, the width of that integer isn't
automatically converted and then we'll get a partial valume.

This fix following problem:

sheep -w size=1T # which will overflow a 32bit integer
dog vdi cache info # will get a wrong value
