rrd_first_r leave file descriptor open on error

[TvE]

In rrd_first.c on line 71 the error return statement leaves the RRD file descriptor open. Lines 69-71 should be changed from:

    if((rraindex < 0) || (rraindex >= (int)rrd.stat_head->rra_cnt)) {
        rrd_set_error("invalid rraindex number");
        return(-1);
    }

to:

    if((rraindex < 0) || (rraindex >= (int)rrd.stat_head->rra_cnt)) {
        rrd_set_error("invalid rraindex number");
        rrd_free(&rrd);
        fclose(in_file);
        return(-1);
    }
