[GIT PULL] nvme fixes for 4.18

[hch@infradead.org (Christoph Hellwig)]

Fix various little regressions introduced in this merge window, plus
a rework of the fibre channel connect and reconnect path to share the
code instead of having separate sets of bugs.  Last but not least a
trivial trace point addition from Hannes.
