inotify: convert to idr_alloc()
Convert to the much saner new idr interface. Note that the adhoc cyclic id allocation is buggy. If wraparound happens, the previous code with idr_get_new_above() may segfault and the converted code will trigger WARN and return -EINVAL. Even if it's fixed to wrap to zero, the code will be prone to unnecessary -ENOSPC failures after the first wraparound. We probably need to implement proper cyclic support in idr.
