jffsX-utils: jffs2reader: Fix potential null pointer dereference compiling warning for 'path'
The compiler compains following message:
jffsX-utils/jffs2reader.c:697:6: warning: potential null pointer
dereference
It won't bring any problems because the 'path' is guaranteed to be a
non-NULL variable. Fix the warning by adding a NULL pointer check.
