mac80211_hwsim: check HWSIM_ATTR_RADIO_NAME length
[ Upstream commit ff4dd73dd2b4806419f8ff65cbce11d5019548d0 ]
Unfortunately, the nla policy was defined to have HWSIM_ATTR_RADIO_NAME
as an NLA_STRING, rather than NLA_NUL_STRING, so we can't use it as a
NUL-terminated string in the kernel.
Rather than break the API, kasprintf() the string to a new buffer to
guarantee NUL termination.
