icmp: standardize naming of RFC 8335 PROBE constants
The current definitions of constants for PROBE, currently defined only in the net-next kernel branch, are inconsistent, with some beginning with ICMP and others with simply EXT. This patch attempts to standardize the naming conventions of the constants for PROBE before their release into a stable Kernel, and to update the relevant definitions in net/ipv4/icmp.c. Similarly, the definitions for the code field (previously ICMP_EXT_MAL_QUERY, etc) use the same prefixes as the type field. This patch adds _CODE_ to the prefix to clarify the distinction of these constants.
