SMB3: Fix crash in SMB2_open_init due to uninitialized field in compounding path
Steve French authored 
Ran into an intermittent crash in
	SMB2_open_init+0x2f6/0x970
due to oparms.cifs_sb not being initialized when called from:
	smb2_compound_op+0x45d/0x1690
Zero the whole oparms struct in the compounding path before setting up the
oparms so we don't risk any uninitialized fields.

Fixes: fdef665b

 ("smb3: fix mode passed in on create for modetosid mount option")

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.
