Jakub Kicinski b0672895d8 net: genl: fix error path memory leak in policy dumping ... commit 249801360d upstream. If construction of the array of policies fails when recording non-first policy we need to unwind. netlink_policy_dump_add_policy() itself also needs fixing as it currently gives up on error without recording the allocated pointer in the pstate pointer.
