Add correct way to check if buffer can be sent to hw in below cases.
1. buffer handle mapped twice, resulting into two entries in buf_q.
One entry without smmu mapping and one with smmu mapping.
fixed by checking if another entry with smmu map exists for i_no.
2. blob cmd buffer, packet buffer are shared only between umd and kmd.
send_buffer_to_presil expected to be called and return success.
