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.
