Fix bad speed settings interaction.

Browse Source 
The flag x->skip_recode interacts badly with
the cpi->sf.use_nonrd_pick_mode and
cpi->sf.skip_encode_sb speed settings.

Restricting the use of the skip_decode flag when
these other speed choices are in use helps quality
for speeds 3 and 4 by a large amount with only a
small impact on speed.

Average improvmentes for 2 pass speed 4:
Derf +8.8%
Yt + 10.53%
Std-Hd +6.95%
yt-hd + 22.95%
