mm: vmscan: correct nr_requested tracing in scan_folios
When enabling vmscan tracing, it is observed that nr_requested is always
4096, which is confusing.
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
mm_vmscan_lru_isolate: classzone=3 order=0 nr_requested=4096 ...
This is because it prints MAX_LRU_BATCH, which is meaningless as it's a
constant. To fix this, modify it to print capped valued.
