yilingjin 918a511742 sli: fix crash when open the sli.monitor file in rw mode 
When the {cpuacct/memory/blkio}.sli.monitor file is opened in rw mode, the
inode->i_readcount will not be increased. However, sli_monitor_open
will force change f_mode to FMODE_READ, this will lead to a crash when
trying to decrease the i_readcount in put_file_access. This problem is
caused by d6da19c9ca ("locks: fix TOCTOU race when granting write lease")
moving i_readcount_inc before open.
This commit fixes the bug by deleting the operation that forces the f_mode
to be changed to FMODE_READ in sli_monitor_open.

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.
