What is the meaning of this command in PBR ---- Set IP next-hop availability.?

In this case the router checks that the next hop address is reachable before setting the next hop.

If PBR confirms that the specified next hop is not available then it does not set the next hop to that value.

It should have 192.168.30.10 rechable to use 10.8.12.20 next hop.
