[blktests v3 0/2] Test multipath and marginal ports

Tests for the upcoming nvme-fc: FPIN link integrity handling set.
It tests for various multipath and marginal port
scenarios, while confirming the port usage and state. The test is
intended to emulate receiving an FPIN event in a multipath environment.

In V3 various generic link checking code was move to common/nvme.
This is so that it can be used by other tests to check if multipath
working correctly, even on kernels that dont support marginal paths.
