As smc_diag.h is bundled, there is little sense to build AF_SMC support
conditionally.
* netlink_smc_diag.c [!AF_SMC]: Include xlat/addrfams.h under
XLAT_MACROS_ONLY, enable the rest of file.
* netlink_sock_diag.c: Include xlat/addrfams.h under XLAT_MACROS_ONLY.
(diag_decoders): Remove "ifdef AF_SMC" condition for [AF_SMC], reorder
in accordance with address family values.
* tests/nlattr_smc_diag_msg.c [!AF_SMC]: Define AF_SMC to 43, enable
the rest of test.
Print trailing dots instead of silent truncation if the array
is too long.
* netlink_sock_diag.c (decode_meminfo): Do not apply SK_MEMINFO_VARS
limit to nmemb, specify element count to print_array instead.

if the element count exceeds SK_MEMINFO_VARS.

Add const qualifiers to auto variables and function arguments.
This change does not affect the code generated by the compiler,
the purpose of these "const" qualifiers is to highlight the intent.
