Replace kcalloc() followed by copy_from_user() with memdup_array_user() to improve and simplify both __qaic_execute_bo_ioctl() and qaic_perf_stats_bo_ioctl(). In __qaic_execute_bo_ioctl(), return early if an error occurs and remove the obsolete 'free_exec' label. Since memdup_array_user() already checks for multiplication overflow, remove the manual check in __qaic_execute_bo_ioctl(). Remove any unused local variables accordingly. Since 'ret = copy_from_user()' has been removed, initialize 'ret = 0' to preserve the same return value on success. No functional changes intended.

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 reStructuredText 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.
