Drivers: hv: Resolve ambiguity in hypervisor version log

Browse Source 
Update the log message in hv_common_init to explicitly state that the
reported version is for the Microsoft Hypervisor, not the host OS.

Previously, this message was accurate for guests running on Windows
hosts, where the host and hypervisor versions matched. With support for
Linux hosts running the Hyper-V hypervisor, the host OS and hypervisor
versions may differ.

This change avoids confusion by making it clear that the version refers to
the Microsoft Hypervisor regardless of the host operating system.
