    fs: PM: Fix reverse check in filesystems_freeze_callback()
    
    The freeze_all_ptr check in filesystems_freeze_callback() introduced by
    commit a3f8f8662771 ("power: always freeze efivarfs") is reverse which
    quite confusingly causes all file systems to be frozen when
    filesystem_freeze_enabled is false.
    
    On my systems it causes the WARN_ON_ONCE() in __set_task_frozen() to
    trigger, most likely due to an attempt to freeze a file system that is
    not ready for that.
    
    Add a logical negation to the check in question to reverse it as
    appropriate.
