[PATCH 2/2] Staging: hv: Zero out the request structure on allocation

["K. Y. Srinivasan" <kys@microsoft.com>]

As part of the cleanup of the I/O request structure, allocate them zeroed
out. This fixes a bug that was introduced in the patch-set titled:
Staging: hv: Cleanup-storage-drivers-phase-II.
A corrected version of this patch-set was sent out earlier, however
the earlier (buggy) version of this patch-set was already applied.
This patch fixes the problem.
