flow_dissector: fix byteorder of dissected ICMP ID
flow_dissector_key_icmp::id is of type u16 (CPU byteorder),
ICMP header has its ID field in network byteorder obviously.
Sparse says:
net/core/flow_dissector.c:178:43: warning: restricted __be16 degrades to integer
Convert ID value to CPU byteorder when storing it into
flow_dissector_key_icmp.
Fixes: 5dec597e5cd0 ("flow_dissector: extract more ICMP information")
