In ovpn_nl_key_swap_doit, the attributes array used to parse the
OVPN_A_KEYCONF uses OVPN_A_PEER_MAX instead of
OVPN_A_KEYCONF_MAX. Note that this does not cause any bug, since
currently OVPN_A_KEYCONF_MAX < OVPN_A_PEER_MAX.

Fixes: 203e2bf55990 ("ovpn: implement key add/get/del/swap via netlink")

This patch is not urgent since the array ends up being too big for our
needs, so there is no bug.
