selftests/mm: fix uffd-stress unused function warning
Patch series "A minor flurry of selftest/mm fixes", v3.
A series that fixes up build errors and warnings for at least the 64-bit
builds on x86 with clang.
The series also includes an optional "improvement" of moving some uffd
code into uffd-common.[ch], which is proving to be somewhat controversial,
and so if that doesn't get resolved, then patches 9 and 10 may just get
dropped. They are not required in order to get a clean build, now that
"make headers" is happening.

This patch (of 11):
uffd_minor_feature() was unused. Remove it in order to fix the associated
clang build warning.
