lockdep: remove task argument from debug_check_no_locks_held
The only existing caller to debug_check_no_locks_held calls it with 'current' as the task, and the freezer needs to call debug_check_no_locks_held but doesn't already have a current task pointer, so remove the argument. It is already assuming that the current task is relevant by dumping the current stack trace as part of the warning. This was originally part of 6aa9707099c (lockdep: check that no locks held at freeze time) which was reverted in dbf520a9d7d4.
