tools/testing/selftests: fix gup_longterm for unknown fs
Commit 66bce7afbaca ("selftests/mm: fix test result reporting in
gup_longterm") introduced a small bug causing unknown filesystems to
always result in a test failure.
This is because do_test() was updated to use a common reporting path, but
this case appears to have been missed.
This is problematic for e.g. virtme-ng which uses an overlayfs file
system, causing gup_longterm to appear to fail each time due to a test
count mismatch:
# Planned tests != run tests (50 != 46)
# Totals: pass:24 fail:0 xfail:0 xpass:0 skip:22 error:0
The fix is to simply change the return into a break.
