[portsorch] Make exception handling when Remove Bridge fails

[inspurSDN]

Why I did it Add static mac 00:00:00:01:01:01 to Ethernet1 (Vlan 100 member) and remove Ethernet1 from Vlan 100, then orchagent process would crash

Jun 28 05:35:41.148167 DUT-1 ERR swss#orchagent: :- meta_generic_validation_remove: object 0x3a000000000a97 reference count is 1, can't remove Jun 28 05:35:41.148167 DUT-1 ERR swss#orchagent: :- removeBridgePort: Failed to remove bridge port Ethernet1 from default 1Q bridge, rv:-17 Jun 28 05:35:41.148174 DUT-1 ERR swss#orchagent: :- handleSaiRemoveStatus: Encountered failure in remove operation, exiting orchagent, SAI API: SAI_API_BRIDGE, status: SAI_STATUS_OBJECT_IN_USE Jun 28 05:35:42.586693 DUT-1 ERR swss#supervisor-proc-exit-listener: orchagent process crash in swss container

What I did Make exception handling when Remove Bridge fails, still let it sync, but try to delete BridgePort again when vlanMember has been deleted.
