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.
