176fc7dd15 Redo fix for incorrect vlan parsing of rx emuldev frames
The previous fix in 6977278654 was incorrect and incomplete since it
won't handle the case when emulated devices have PRIO and/or CFI/DEI
set.

This is the correct fix where Prio and CFI/DEI are no longer part of the
device key.

f0dd0c307b Fix device emulation crash due to contention
Device emulation packets are received and processed in a different
thread compared to the main RPC processing thread where the emulated
devices are created/deleted. No packets should be processed while the
latter is in progress otherwise the former may access devices that have
been deleted.

635ca18bce Fix duplicate deletion of host devices
Since host devices are also included in the deviceList_, they are already
being deleted. Deleting them again causes a segfault.
