And use the proper VFS helper for using the backing file.
Also make sure we hold ashmem_lock while updating f_pos to make sure that
it's not racy.

This patch replaces several instances where a pointer is compared to NULL
(i.e., `ptr == NULL`) with `!ptr`, which is preferred.

Currently, the duplicated sg table is freed in the detach() and
the error path of map_dma_buf() ion's dma_buf_ops.
If a call to dma_buf_map_attachment() fails, the importer is
expected to call dma_buf_detach() to remove the attachment. This
will result in us trying to free the duped sg table twice.
Don't call free_duped_table() in ion_map_dma_buf() to avoid this.

Pull staging/IIO updates from Greg KH:
"Here is the big staging tree update for 4.12-rc1.
It's a big one, adding about 350k new lines of crap^Wcode, mostly all
in a big dump of media drivers from Intel. But there's other new
drivers in here as well, yet-another-wifi driver, new IIO drivers, and
a new crypto accelerator.
We also deleted a bunch of stuff, mostly in patch cleanups, but also
the Android ION code has shrunk a lot, and the Android low memory
killer driver was finally deleted, much to the celebration of the -mm
developers.
All of these have been in linux-next with a few build issues that will
show up when you merge to your tree"
Merge conflicts in the new rtl8723bs driver (due to the wifi changes
this merge window) handled as per linux-next, courtesy of Stephen
Rothwell.
