[FFmpeg-cvslog] Fix segfault in save_bits:

[Sascha Sommer]

ffmpeg | branch: master | Sascha Sommer <saschasommer at freenet.de> | Sat Sep 24 20:56:41 2011 +0200| [780d45473c32fa356c8ce385c3ea4692567c3228] | committer: Sascha Sommer

Fix segfault in save_bits:
use put_bits_count to get the buffer fill state instead of
num_saved_bits as num_saved_bits is sometimes reset when
frames are lost
(Ticket 495)
