[PATCHv3 2/4] abbrev_sha1_in_line: don't leak memory

[Stefan Beller <sbeller@google.com>]

`split` is of type `struct strbuf **`, and currently we are leaking split
itself as well as each element in split[i]. We have a dedicated free
function for `struct strbuf **`, which takes care of freeing all
related memory.

Notes:
    Feel free to drop this patch and use the
    the proposal, which drops `**split` entirely
