Michael Li 132c6e934a Reload BCM SDK kmods on syncd start to handle syncd restart issues (#12804)
Why I did it
There is an issue on the Arista PikeZ platform (using T3.X2: BCM56274) while running SONiC. If the 'syncd' container in SONiC is restarted, the expected behaviour is that syncd will automatically restart/recover; however it does not and always fails at create_switch due to BCM SDK kmod DMA operation cancellation getting stuck.

Sep 16 22:19:44.855125 pkz208 ERR syncd#syncd: [none] SAI_API_SWITCH:platform_process_command:428 Platform command "init soc" failed, rc = -1. Sep 16 22:19:44.855206 pkz208 INFO syncd#supervisord: syncd CMIC_CMC0_PKTDMA_CH4_DESC_COUNT_REQ:0x33#015 Sep 16 22:19:44.855264 pkz208 CRIT syncd#syncd: [none] SAI_API_SWITCH:platformInit:1909 initialization command "init soc" failed, rc = -1 (Internal error).

Reloading the BCM SDK kmods allows the switch init to continue properly.

How I did it
If BCM SDK kmods are loaded, unload and load them again on syncd docker start script.

How to verify it
Steps to reproduce:

In SONiC, run 'docker ps' to see current running containers; 'syncd' should be present.
Run 'docker stop syncd'
Wait ~1 minute.
Run 'docker ps' to see that syncd is missing.
Check logs to see messages similar to the above.
