Fix NULL pointer dereference when num_unpins is 0, which causes job->addr_phys to be NULL. In this case, the code was incorrectly trying to set job->gather_addr_phys to &job->addr_phys[num_relocs], which would dereference a NULL pointer. Add proper NULL checks to prevent this issue both during allocation and when using job->gather_addr_phys throughout the code.
