powerpc/powernv: Add error handling to opal_prd_range_is_valid

Browse Source 
In the opal_prd_range_is_valid function within opal-prd.c,
error handling was missing for the of_get_address call.
This patch adds necessary error checking, ensuring that the
function gracefully handles scenarios where of_get_address fails.
