[ Upstream commit ea1d166fae14e05d49ffb0ea9fcd4658f8d3dcea ]
The iwl_fw_ini_debug_info_tlv is used as a string, so we must
ensure the string is terminated correctly before using it.

commit cf4a0d840ecc72fcf16198d5e9c505ab7d5a5e4d upstream.
iwl_fw_ini_trigger_tlv::data is a pointer to a __le32, which means that
if we copy to iwl_fw_ini_trigger_tlv::data + offset while offset is in
bytes, we'll write past the buffer.
