    flxdec: fix some warnings comparing unsigned < 0

    bf43f44fcfada5ec4a3ce60cb374340486fe9fac was comparing an unsigned
    expression to be < 0 which was always false.

    gstflxdec.c: In function ‘flx_decode_brun’:
    gstflxdec.c:322:33: warning: comparison of unsigned expression < 0 is
always false [-Wtype-limits]
             if ((glong) row - count < 0) {
                                     ^
    gstflxdec.c:332:33: warning: comparison of unsigned expression < 0 is
always false [-Wtype-limits]
             if ((glong) row - count < 0) {
                                     ^
