nic_loopback: Adjust to packet allocator changes

Browse Source 
Remove '_expected_offset' check on round trip test from RX packet,
because allocators between RX/TX can have different allocation
strategies. Rely on 'pattern' check for RX packets only.

In loopback server alloc size must match actual packet size.
