[PATCH] iw: scan: fix double-free in error paths

[Brian Norris <briannorris@xxxxxxxxxxxx>]

Hit when, for instance, I'm stupid enough to type an invalid scan
command:

  # iw wlan0 scan -h
  BUG at file position lib/msg.c:572:void nlmsg_free(struct nl_msg *)
  iw: lib/msg.c:572: void nlmsg_free(struct nl_msg *): Assertion `0' failed.
  Aborted (core dumped)

Fixes: 2f74c59cf11e ("iw: fix memory leaks inside handle_scan")
