From: Sriram R <quic_srirrama@quicinc.com>
Currently, the unsolicited probe response template is always fetched from
the default link of a virtual interface in both Multi-Link Operation (MLO)
and non-MLO cases. However, in the MLO case there is a need to fetch the
unsolicited probe response template from a specific link instead of the
default link.
Hence, add support for fetching the unsolicited probe response template
based on the link ID from the corresponding link data.
