This is intentional, because the caller of this API does not care whether VFIO is supported at all, and will instead be interested in whether VFIO is enabled or not. However, the doxygen comments for these functions state that they will return an error on FreeBSD, which is incorrect. Fix the doxygen comment to call out the fact that these functions are only relevant on Linux, but remove the reference to returning errors.
