    GSSubprocess: remove unnecessary NULL check (trivial)
    
    This fixes a warning found during Coverity scan.
    
      Error: REVERSE_INULL (CWE-476): [#def5]
      libgsystem/gsystem-subprocess.c:949: deref_ptr_in_call: Dereferencing pointer "context".
      libgsystem/gsystem-subprocess-context.c:330:3: deref_parm: Directly dereferencing parameter "self".
      libgsystem/gsystem-subprocess.c:960: check_after_deref: Null-checking "context" suggests that it may be 
null, but it has already been dereferenced on all paths leading to the check.
