[PATCH] hyperv: Fix compilation issue with 4.4.19-rt27

[Juerg Haefliger <juerg.haefliger@hpe.com>]

Fix a compilation issue introduced by upstream commit
4b44f2d18a330565227a7348844493c59366171e

The upstream commit exports the symbol add_interrupt_randomness()
which is now being used in the Hyper-V driver. The RT patch adds another
argument to that function so its usage in the Hyper-V driver needs to
be fixed.

This patch should be merged with:
patches/0216-random-Make-it-work-on-rt.patch
commit 20985550b01a21ba00a587d17d7c26da61e01acc random: Make it work on rt
