x86/insn-eval: Mark expected switch-case fall-through
In preparation to enable -Wimplicit-fallthrough by default, mark
switch-case statements where fall-through is intentional, explicitly.
Thus fix the following warning:
arch/x86/lib/insn-eval.c: In function ‘resolve_default_seg’:
arch/x86/lib/insn-eval.c:179:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (insn->addr_bytes == 2)
^
arch/x86/lib/insn-eval.c:182:2: note: here
case -EDOM:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This is part of the ongoing efforts to enable -Wimplicit-fallthrough by
default.
