Wesley Sheng 083c1b5e50 switchtec: Fix unintended mask of MRPC event 
When running application tool switchtec-user's `firmware update` and `event
wait` commands concurrently, sometimes the firmware update speed reduced
significantly.

It is because when the MRPC event happened after MRPC event occurrence
check but before the event mask loop reaches its header register in event
ISR, the MRPC event would be masked unintentionally.  Since there's no
chance to enable it again except for a module reload, all the following
MRPC execution completion checks time out.

Fix this bug by skipping the mask operation for MRPC event in event ISR,
same as what we already do for LINK event.

Fixes: 52eabba5bc ("switchtec: Add IOCTLs to the Switchtec driver")

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.
