In sparse_checkout_init(), we first try to load patterns from an
existing file. If we found any, we return immediately, but end up
leaking the patterns we parsed. Fixing this reduces the number of leaks
in t7002 from 9 down to 5.
Note that there are two other exits from the function, but they don't
need the same treatment:
- if we can't resolve HEAD, we write out a hard-coded sparse file and
return. But we know the pattern list is empty there, since we didn't
find any in the on-disk file and we haven't yet added any of our
own.
- otherwise, we do populate the list and then tail-call into
write_patterns_and_update(). But that function frees the
pattern_list itself, so we don't need to.
