patch 9.1.2090: Last buffer not freed with EXITFREE
Problem: Last buffer not freed with EXITFREE (after 9.1.2087).
Solution: Free the last buffer when inside free_all_mem()
(zeertzjq).
This isn't really a memory leak, as the last buffer's memory is still
reachable via pointers like firstbuf and lastbuf. But it's possible that
this may cause false ASAN warnings in the future, which is what EXITFREE
is supposed to prevent.
