mem_buf_retrieve() is what will actually create a DMA-BUF, along with
the struct file that underpins the DMA-BUF's lifetime and user space
interface. The FD RWX permissions are set during this time, and
currently, we just supply a flags value of 0, corresponding to
read-only. Set the file permissions as O_RDWR accordingly.
Separately, dma_buf_fd(), which just exposes a DMA-BUF's struct file
to user space, ignores all other arguments other than O_CLOEXEC, so
discard the other arguments.

Proxy map calls on a locked and already-mapped buffer should succeed.
Re-arrange state checks in retrieve_and_iommu_map() to ensure this.
