Randy Li c56a9365f6 [ion]: file descriptor for the external buffer ...

The imported buffer may be released from its origin allocator,
I would suggest to use the new file descriptor from new ion
handle.

The ion only has map_user() to export buffer to userspace,
There is no unmap_user() because the mapping is represented as
a file descriptor in user space. The closing of that file
descriptor will cause the memory to be unmapped from
the calling process.
