[media] stb0899: Fix slow and not locking DVB-S transponder(s)
In stb0899_status stb0899_check_data the first read of STB0899_VSTATUS
could read old (from previous search) LOOP status bit and the search
fails on a good frequency.
With the patch more transponder could be locked and locks about 2*
faster.
