[PATCH] stb0899: Fix slow and not locking DVB-S transponder(s)



Another version of
http://patchwork.linuxtv.org/patch/6307
http://patchwork.linuxtv.org/patch/6510
which was superseded or rejected, but it don't know why.

In stb0899_status stb0899_check_data the first read of STB0899_VSTATUS
could read old (from previous search) status bits and the search fails
on a good frequency.

With the patch more transponder could be locked and locks about 2* faster.
