video: adf: build fixes for 4.1

Browse source 
Couple of ADF build fixes for v4.1

adf/adf_fops.c fix:
get_unused_fd() is obsolete, use get_unused_fd_flags(O_CLOEXEC)
instead to allocate a default file descriptor. This fix is a
followup of upstream commit f938612dd9 "include/linux/file.h:
remove get_unused_fd() macro".

adf/adf_memblock.c fix:
Fix dma_buf_export() call. Based on mainline commit d8fbe341be
"dma-buf: cleanup dma_buf_export() to make it easily extensible".

Otherwise we run into following build failures:
