android: ion: remove the list of attachments

dma_buf also has the list of attachments. ion_buffer.attachments is
redundant. So, let's remove it.
dma_buf.attachment should be accessed with dma_buf.lock held. Holding
dma_buf.lock in begin_cpu_access() and end_cpu_access() is okay. But
it should be handled with care to prevent possible deadlock.
