apply: plug a leak in apply_data
We have an execution path in apply_data that leaks the local struct
image. Plug it.
This leak can be triggered with:
$ echo foo >file
$ git add file && git commit -m file
$ echo bar >file
$ git diff file >diff
$ sed s/foo/frotz/ <diff >baddiff
$ git apply --cached <baddiff
Fixing this leak allows us to mark as leak-free the following tests:
+ t2016-checkout-patch.sh
+ t4103-apply-binary.sh
+ t4104-apply-boundary.sh
+ t4113-apply-ending.sh
+ t4117-apply-reject.sh
+ t4123-apply-shrink.sh
+ t4252-am-options.sh
+ t4258-am-quoted-cr.sh
Mark them with "TEST_PASSES_SANITIZE_LEAK=true" to notice and fix
promply any new leak that may be introduced and triggered by them in the
future.
