09f363c7 fixed shrinker callback returns -1 when nr_to_scan is zero
for preventing excessive the slab scanning. But 635697c6 fixed the
problem, again so we can freely return -1 although nr_to_scan is zero.
So let's revert 09f363c7 because the comment added in 09f363c7 made a
unnecessary rule shrinker user should be aware of.

Please also include the subject of the commit, not just raw hash number. ;)

For example,

09f363c7("vmscan: fix shrinker callback bug in fs/super.c")
635697c6("vmscan: fix initial shrinker size handling")
