Lorenzo Stoakes 21c68ad1d9 tools/testing/selftests: fix gup_longterm for unknown fs 
Commit 66bce7afba ("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.
