scpi: make sure to either return valid SCPI response data or NULL

Assign NULL early in those SCPI get routines which return allocated
memory to their callers. So that the return value is either a valid
pointer to memory or NULL regardless of the routine's exit code. This
simplifies call sites and increases robustness.
