LINEAR_RGB_InitSCCData: When malloc fails, don't try to free unallocated bits
One of the malloc failure checks had a goto to the wrong spot in the list of cleanup free() calls to unwind at the end, and was freeing bits that hadn't been initialized/allocated yet, since they would be stored in the struct that just failed to be allocated. Error: Null pointer dereference (CWE 476) Read from pointer that could be constant 'NULL' at line 805 of /export/alanc/X.Org/sx86/lib/libX11/nx-X11/lib/X11/LRGB.c in function 'LINEAR_RGB_InitSCCData'. Pointer checked against constant 'NULL' at line 754 but does not protect the dereference. [ This bug was found by the Parfait bug checking tool.
