The return type of wait_for_completion_timeout is unsigned long not
int. This patch resolves the type missmatch by changing the type
to unsigned long.

This patch was only compile tested with x86_64_defconfig +
CONFIG_X86_VSMP=y, CONFIG_HYPERV=m, CONFIG_HYPERV_BALLOON=m

Patch is against 3.19.0-rc6 -next-20150130
