Jonathan Curley f15ebc876f NFSv4/flexfiles: Fix layout merge mirror check. ...

[ Upstream commit dd2fa82473 ]

Typo in ff_lseg_match_mirrors makes the diff ineffective. This results
in merge happening all the time. Merge happening all the time is
problematic because it marks lsegs invalid. Marking lsegs invalid
causes all outstanding IO to get restarted with EAGAIN and connections
to get closed.

Closing connections constantly triggers race conditions in the RDMA
implementation...
