range-diff: plug memory leak in common invocation
Create a public release_patch() version of the private free_patch()
function added in 13b5af22f39 (apply: move libified code from
builtin/apply.c to apply.{c,h}, 2016-04-22). Unlike the existing
function this one doesn't free() the "struct patch" itself, so we can
use it for variables on the stack.
Use it in range-diff.c to fix a memory leak in common range-diff
invocations, e.g.:
git -P range-diff origin/master origin/next origin/seen
Would emit several errors when compiled with SANITIZE=leak, but now
runs cleanly.
