René Scharfe 76d8d45ffb coccinelle: polish FREE_AND_NULL rules
There are two rules for using FREE_AND_NULL in free.cocci, one for
pointer types and one for expressions.  Both cause coccinelle to remove
empty lines and even newline characters between replacements for some
reason; consecutive "free(x);/x=NULL;" sequences end up as multiple
FREE_AND_NULL calls on the same time.

Remove the type rule, as the expression rule already covers it, and
rearrange the lines of the latter to place the addition of FREE_AND_NULL
between the removals, which causes coccinelle to leave surrounding
whitespace untouched.
