ANDROID: sdcardfs: Directly pass lower file for mmap
Instead of relying on a copy hack, pass the lower file
as private data. This lets the kernel find the vma
mapping for pages used by the file, allowing pages
used by mapping to be reclaimed.
This is adapted from following esdfs patches
commit 0647e638d: ("esdfs: store lower file in vm_file for mmap")
commit 064850866: ("esdfs: keep a counter for mmaped file")
