[PATCH v3 1/2] bhyve: Separate out checks from virBhyveProbeCaps

[Roman Bogorodskiy <bogorodskiy@xxxxxxxxx>]

From: Fabian Freyer <fabian.freyer@xxxxxxxxxxxxxxxxxxx>

At the moment this is just one check, but separating this out into a
separate function makes checks more modular, allowing for more readable
code once more checks are added. This also makes checks more easily
testable.
