Subject: [PATCH 12/16] arch: x86: kernel: Add prototype for fixup_bad_iret in traps.c

traps.c defines the function fixup_bad_iret used in this file only
and in some assembly. No header file declares this function so,
add a prototype for fixup_bad_iret above the function definition.

This also satisfies the following gcc(-Wmissing-prototypes) warning:
arch/x86/kernel/traps.c:500:24: warning: no previous prototype for ‘fixup_bad_iret’ [-Wmissing-prototypes]
