[JFFS2] Remove number of pointer dereferences in fs/jffs2/summary.c

Reduce the nr.  of pointer dereferences in fs/jffs2/summary.c

Benefits:
 - micro speed optimization due to fewer pointer derefs
 - generated code is slightly smaller
 - better readability

(The first two sound like a compiler problem but I'll go with the third. dwmw2).
