Subject: [PATCH 1/2] mshv: rename synic per-cpu init/cleanup functions

From: Anirudh Rayabharam (Microsoft) <anirudh@...rudhrb.com>

Rename mshv_synic_init() to mshv_synic_cpu_init() and
mshv_synic_cleanup() to mshv_synic_cpu_exit() to better reflect that
these functions handle per-cpu synic setup and teardown.

This prepares for a future patch that will introduce mshv_synic_init()
and mshv_synic_cleanup() for common, non per-cpu initialization.

No functional change.
