eatqi: move "block" variable into context to ensure sufficient alignment for
idct_put for compilers/architectures that can not align stack variables that much.
This is also consistent with similar code in eatgq.c

Originally committed as revision 18927 to svn://svn.ffmpeg.org/ffmpeg/trunk
(cherry picked from commit 1eda87ce6366189eebf9956f826dfd92d9e64d9c)
