While removing an smb session, we need to free up the tcp session for each channel for that session. We were doing this with chan_lock held. This results in a cyclic dependency with cifs_tcp_ses_lock. For now, unlock the chan_lock temporarily before calling cifs_put_tcp_session. This should not cause any problem for now, since we do not remove channels anywhere else. And this code segment will not be called by two threads. When we do implement the code for removing channels, we will need to execute proper ref counting here.

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.
