    libX11: do not crash in GetResReq() macro
    
    When _XGetRequest() detects that requested length exceeds remaining display
    output buffer capacity it would return NULL. GetResReq() macro obtains "req"
    pointer from a call to _XGetRequest() and then proceeds to assign request id
    through "req" pointer which leads to NULL pointer dereference in this case.
    
    Fix this by checking if "req" is valid before assigning request id.
