Prevent a crash from occurring when a jitter buffer interpolated frame is
removed from a slinfactory

slinfactory used the "samples" field of an ast_frame in order to determine
the amount of data contained within the frame. In certain cases, such as
jitter buffer interpolated frames, the frame would have a non-zero value
for
"samples" but have NULL "data"

This caused a problem when a memcpy call in ast_slinfactory_read would
attempt
to access invalid memory. The solution in use here is to never feed frames
into
the slinfactory if they have NULL "data"
