Context bit is set for hardware execution if there is a buffer
in source and destination queue before calling try_run in the
init_buffers function. Now there will be a new context created
and hardware will be invoked for the buffer queued instead of
waiting for another buffer to be queued from userspace to set
this context bit for hw execution.
