x86/mce: Mark mce_panic() noinstr

[ Upstream commit 3c7ce80a818fa7950be123cac80cd078e5ac1013 ]

And allow instrumentation inside it because it does calls to other
facilities which will not be tagged noinstr.

Fixes

  vmlinux.o: warning: objtool: do_machine_check()+0xc73: call to mce_panic() leaves .noinstr.text section
