[submodule]: Updating sonic-swss (#6685)

Changed Error log to Notice log during FDB flush notification after VLAN delete (#1618) 288fb40

- How to verify it
Create a VLAN and add member port to it. Then inject traffic on the member port for that VLAN. Ensure that FDB entry is learnt for that VLAN member port. Then remove the member port and remove VLAN. Check if you get a NOTICE log that "failed to locate VLAN" appears in syslogs.
