apparmor: fix memory leak on buffer on error exit path
Currently on the error exit path the allocated buffer is not free'd
causing a memory leak. Fix this by kfree'ing it.
Detected by CoverityScan, CID#1466876 ("Resource leaks")
Fixes: 1180b4c757aa ("apparmor: fix dangling symlinks to policy rawdata after replacement")
