sound-file-stream: Fix crash when playing a file which is not aligned

Jaechul Lee requested to merge jcsing.lee/pulseaudio:push_align into master

pulseaudio crash occurred when I play a file using pacmd play-file command. The file is not aligned with its frame size and the last rendering size is also not aligned. Thus, an assertion was generated at the end of the file as the following.

memblockq.c: Assertion 'uchunk->length % bq->base == 0' failed at ../src/pulsecore/memblockq.c:288, function pa_memblockq_push(). Aborting.

When I play the file using paplay, it works good. So, I changed to pa_memblockq_push_align instead of pa_memblockq_push to prevent the assertion. Signed-off-by: Jaechul Lee's avatarJaechul Lee jcsing.lee@samsung.com
