iio: buffer: use dma_buf_unmap_attachment_unlocked() helper
Replace open-coded dma_resv_lock()/dma_resv_unlock() around
dma_buf_unmap_attachment() in iio_buffer_dmabuf_release() with the
dma_buf_unmap_attachment_unlocked() helper.
This aligns with the standard DMA-BUF API, avoids duplicating
locking logic and eases future maintenance. No functional change.
