Subject: ip: Wrap CASE macro body in braces for pre-C23 compatibility

Compiling on RHEL8 (gcc-8.5) gives an error in ip.c.
ip.c:88:3: error: a label can only be part of a statement and
a declaration is not a statement due to the use of static_assert.

The fix is to surround it with {}.

Fixes: 93c3e351f235 ("ip: Define a bound for the string returned by ipproto_name()")
