remote: drop free_refspecs() function

We already have free_refspec(), a public function which does the same thing as the static free_refspecs(). Let's just keep one. There are two minor differences between the functions: 1. free_refspecs() is a noop when the refspec argument is NULL. This probably doesn't matter in practice. The nr_refspec parameter would presumably be 0 in that case, skipping the loop. And free(NULL) is explicitly OK. But it doesn't hurt for us to port this extra safety to free_refspec(), as one of the callers passes a funny "i+1" count. 2. The order of arguments is reversed between the two functions. This patch uses the already-public order of free_refspec(), as it matches the argument order on the parsing side.
