thunderbolt: Clamp XDomain response data copy to allocation size

In the Linux kernel, the following vulnerability has been resolved:

thunderbolt: Clamp XDomain response data copy to allocation size

tb_xdp_properties_request() derives the per-packet copy length from
the response header without checking that it fits in the previously
allocated data buffer.  A malicious peer can set its length field
larger than the declared data_length, causing memcpy to write past
the kcalloc allocation.

Clamp the per-packet copy length so that the cumulative offset
never exceeds data_len.
