dma-buf: add support for compat ioctl
commit 888022c0473d079bff9b47fb50434b1f20f8f37f upstream. Add compat ioctl support to dma-buf. This lets one to use DMA_BUF_IOCTL_SYNC ioctl from 32bit application on 64bit kernel. Data structures for both 32 and 64bit modes are same, so there is no need for additional translation layer.
