Subject: [PATCH] storvsc: assign wait_for_completion_timeout to appropriately typed var

wait_for_completion_timeout() returns unsigned long not int. This assigns
the return value to an appropriately typed variable.

Signed-off-by: Nicholas Mc Guire <hofrat@...dl.org>
---

As a suitable typed and named variable "timeout" is available and there is
no conflict in this case no new variable is needed rather the declaration
is simply updated.

Patch was only compile tested for x86_64_defconfig + CONFIG_X86_VSMP=y
CONFIG_HYPERV=m, SCSI_LOWLEVEL=y, CONFIG_HYPERV_STORAGE=m

Patch is against 3.19.0-rc7 (localversion-next is -next-20150204)
