This commit removes the local buffer zeros in ks_wlan_get_encode function. It also refactors related conditions in order to fill 'extra' output parameter of the function. Originally this zeros is just memset to zeros and only being used if drw->length is truncated to zero because of priv->reg.wep_key[index].size is greater than 16 chars. In those cases the final if statement is just using zeros but it is using memcpy with a length of zero bytes which has no sense. Instead of that just handle the good case copying from the same source the number of bytes of priv->reg.wep_key[index].size. If it is zero the final 'extra' parameter won't be copied at all because the number of bytes to copy will be zero. With this change the code gets simplified.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
