Subject: [PATCH] x86/entry: don't use kernel-doc for IDTENTRY functions

scripts/kernel-doc doesn't handle DEFINE_IDTENTRY*() variants
so it prints a warning when processing them.

In order to reduce/remove kernel-doc warnings from the kernel, don't
use kernel-doc notation for DEFINE_IDTENTRY*() function comments.
This brings the common.c usage in line with the more than 50 other
uses of DEFINE_IDTENTRY*() in the kernel.

This prevents one warning:

arch/x86/entry/common.c:211: warning: expecting prototype for int80_emulation(). Prototype was for DEFINE_IDTENTRY_RAW() instead
