René Scharfe ec6cd14c7a cocci: detect useless free(3) calls 
Add a semantic patch for removing checks that cause free(3) to only be
called with a NULL pointer, as that must be a programming mistake.

René Scharfe 39ea59a257 remove unnecessary NULL check before free(3) 
free(3) handles NULL pointers just fine.  Add a semantic patch for
removing unnecessary NULL checks before calling this function, and
apply it on the code base.
