Ævar Arnfjörð Bjarmason 2d102c2bca range-diff: plug memory leak in read_patches() ...

Amend code added in d9c66f0b5b (range-diff: first rudimentary
implementation, 2018-08-13) to use a "goto cleanup" pattern. This
makes for less code, and frees memory that we'd previously leak.

The reason for changing free(util) to FREE_AND_NULL(util) is because
at the end of the function we append the contents of "util" to a
"struct string_list" if it's non-NULL.
