When doing some tests with multiple mds, we were seeing many mds forwarding requests between them, causing clients to resend. If the request is a modification operation and the mode is set to USE_AUTH_MDS, then the auth mds should be selected to handle the request. If auth mds for frag is already set, then it should be returned directly without further processing. The current logic is wrong because it only returns directly if mode is USE_AUTH_MDS, but we want to do that for all modes. If we don't, then when the frag's mds is not equal to cap session's mds, the request will get sent to the wrong MDS needlessly. Drop the mode check in this condition.

README
Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
