[PATCH] nvme_fc: revise comment on teardown

[jsmart2021 at gmail.com]

From: James Smart <jsmart2021 at gmail.com>

Per the recommendation by Sagi on:
http://lists.infradead.org/pipermail/linux-nvme/2017-April/009261.html

An extra reference was pointed out.  There's no issue with the
references, but rather a literal interpretation of what the comment
is saying.

Reword the comment to avoid confusion.
