Since cond_resched() is not called in userspace, remove the redundant code in userspace's list_sort() implementation. This change eliminates the unused 'count' variable and the associated logic for invoking cmp() periodically, which was intended to trigger cond_resched() in kernel space. The removed code includes: - Declaration and increment of the 'count' variable. - Conditional invocation of cmp() based on 'count'. This cleanup simplifies merge_final(), avoids unnecessary overhead, and has no impact on the functionality of list_sort() in userspace.
