mm/vmscan: fix inverted polarity in lru_gen_seq_show()

Commit a7694ff11aa9 ("vmscan: don't bother with debugfs_real_fops()")
started using debugfs_get_aux_num() to distinguish between the RW
"lru_gen" and the RO "lru_gen_full" file [1].

Willy reported the inverted polarity [2] and Al fixed it up in [3].

However, the patch in [1] was applied. Hence, fix this up accordingly.
