Arnd Bergmann 6956d8be23 crypto: octeontx2 - fix -Wpointer-bool-conversion warning
When CONFIG_CPUMASK_OFFSTACK is disabled, clang reports a warning
about a bogus condition:

drivers/crypto/marvell/octeontx2/otx2_cptlf.c:334:21: error: address of array 'lfs->lf[slot].affinity_mask' will always evaluate to 'true' [-Werror,-Wpointer-bool-conversion]
                if (lfs->lf[slot].affinity_mask)
                ~~  ~~~~~~~~~~~~~~^~~~~~~~~~~~~

In this configuration, the free_cpumask_var() function does nothing,
so the condition could be skipped.

When the option is enabled, there is no warning, but the check
is also redundant because free_cpumask_var() falls back to kfree(),
which is documented as ignoring NULL pointers.

Remove the check to avoid the warning.

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.
