[Bug]: The ACL reboot testcase need additional check to ensure the PortChannels are Up before Proceeding further

[santoss3]

Issue Description

We have observed with 202405 Image that TestAclWithReboot testcases fail because sometimes PortChannel take a bit more time to come up.
This needs to be addressed by ensuring we wait for PortChannels to come up, after the DUT is rebooted.

Results you see
