[action] [PR:3671] Fixed the issues with sonic-clear queuecounter for egress queue and voq

[mssonicbld]

What I did

Fixed the sonic-clear queuecounter issues reported in sonic-net/sonic-buildimage#20913
Fixed the following 2 issues

1. For the egress queue counters, after the queue counter is cleared and show is issued with --nonzero option, the code takes the elif path at line 323 (old code) even if the diff between cached counter and current counter is 0, prints the current counter values from counter_db . This issue was for both egress queue counter and voq counter.
2. When the sonic-clear queuecounter is issued , the queuestat is called first without --voq option and this gets the port names and queue ids for each port in each asic , reads the egress queue counters and cache the values in /tmp/cache/queuestat/. Then queuestat is called with --voq option and this gets all the system ports names and voq id's for each asic , reads the voq counters and cache the values in /tmp/cache/queuestat. Since each asic has the all the system ports and all the voqs, and since the cache file name is queuestat+system_port_name with out asic namespace, caching asic1's voq counters overwrites the asic0's voq counters .

How I did it

1)Corrected the logic mistake for issue 1. Since cnstat_diff_print is called only if cache file is present and this should print only if non-zero & valid diff or (not non-zero )
2) Added asic namespace with the cache file name for vow counters.

How to verify it

Previous command output (if the output of a command-line utility has changed)

show command output is not changed.

New command output (if the output of a command-line utility has changed)

show command output is not changed.
