[PATCH v2] vfio: platform: ignore missing reset if disabled at module init

[Tomasz Duszynski <tduszynski@marvell.com>]

If reset requirement was relaxed via module parameter errors caused by
missing reset should not be propagated down to the vfio core.
Otherwise initialization will fail.

v2:
- return directly instead of using ternary to do that
