usb: gadget: functionfs: use dma_buf_unmap_attachment_unlocked() helper
Replace the open-coded dma_resv_lock()/dma_resv_unlock() around
dma_buf_unmap_attachment() in ffs_dmabuf_release() with the
dma_buf_unmap_attachment_unlocked() helper.
This aligns FunctionFS DMABUF unmap handling with the standard
DMA-BUF API, avoids duplicating locking logic and eases future
maintenance. No functional change.
