…c-net#16264) What is the motivation for this PR? Default route check in sanity is added by sonic-net#16235 It only supports single asic for now.

Manually cherry-pick this PR: #16264
Default route check in sanity is added by #16235
It only supports single asic for now. But constraint for single asic in recover stage is missed
It would cause keyError in multi-asic if it trys to recover bgp sanity check failure
How did you do it?
Add single asic constraint in recover
How did you verify/test it?
Run test
Any platform specific information?
Supported testbed topology if it's a new test case?
