[PATCH 2/8] x86/hyperv: Add interrupt handler annotations

From: Michael Kelley <mikelley@microsoft.com>

Add standard interrupt handler annotations to
hyperv_vector_handler(). This does not fix any observed
bug, but avoids potential removal of the code by link
time optimization and makes it consistent with
hv_stimer0_vector_handler in the same source file.
