In net/ieee802154/nl-phy.c::ieee802154_nl_fill_phy() I see two small
issues.
1) If the allocation of 'buf' fails we may just as well return -EMSGSIZE
   directly rather than jumping to 'out:' and do a pointless kfree(0).
2) We do not free 'buf' unless we jump to one of the error labels and this
   leaks memory.
This patch should address both.
