net: ice: Fix potential NULL pointer dereference in icebridgesetlink()
The function icebridgesetlink() may encounter a NULL pointer dereference if nlmsgfindattr() returns NULL and brspec is dereferenced subsequently in nlaforeachnested(). To address this issue, add a check to ensure that br_spec is not NULL before proceeding with the nested attribute iteration.
