ioctl.c utilizes memdup_user() to copy a userspace array. An overflow check is performed manually before the function's invocation. The new function memdup_array_user() standardizes copying userspace arrays, thus, improving readability by making it more clear that an array is being copied. Additionally, it also performs an overflow check. Remove the (now redundant) manual overflow-check and replace memdup_user() with memdup_array_user(). In addition, improve the grammar of the comment above memdup_array_user().

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.
