smp: fix SIGSEGV for "smp off" during target examine 

The gdb subsystem is initialized after the first target examine,
so the field struct target::gdb_service is NULL during examine.

A command "smp off" in the examine event handler causes a SIGSEGV
during OpenOCD startup.

Check for pointer not NULL before dereferencing it.
