What I did Fix issue reported in sonic-net#3961. Regression happened after move to bulk implementation. The error handling of no PGs, queues was incorrect. Bulk array preparation and reading should use a consistent approach. For example, if a port is skipped in the input array, it should also be skipped when reading from the output array. Why I did it Fix issue reported in sonic-net#3961.

What I did
Fix issue reported in #3961.
Regression happened after move to bulk implementation. The error handling of no PGs, queues was incorrect.
Bulk array preparation and reading should use a consistent approach. For example, if a port is skipped in the input array, it should also be skipped when reading from the output array.
Why I did it
Fix issue reported in #3961.
How I verified it
Implemented a UT to ensure no crash happens when number of PGs, queues or scheudler group is 0.
