Commit e008b95a28ef95dd4bb08f69c89d26fc5fa7411a
"ms/mm: use sc->priority for slab shrink targets"
exposed the fact we shrinks too many tcache pages.
Shrinkers of {in,}active pages shrink up to 32
pages, while tcache and tswap shrinks 128 pages.
This became a reason of tcache active test fail.
This patch makes numbers of shrinked pages of tcache
and tswap in consistent state with pages shrinkers,
and restores the test-expected behaviour.
