kgdb,x86: fix warning about unused variable

When compiling without CONFIG_DEBUG_RODATA the following compiler warning is generated: arch/x86/kernel/kgdb.c: In function 'kgdb_arch_set_breakpoint': arch/x86/kernel/kgdb.c:749: warning: unused variable 'opc' The variable instantiation needs to be inside the #ifdef to make the warning go away.
