While reading the TCB field in t4_tcb_get_field32() the wrong mask is
passed as a parameter which leads the driver eventually to a kernel
panic/app segfault from access to an illegal SRQ index while flushing the
SRQ completions during connection teardown.
Fixes: 11a27e2121 ("iw_cxgb4: complete the cached SRQ buffers")

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.
