UPSTREAM: Revert "ecryptfs: forbid opening files without mmap handler"
(cherry picked from commit 78c4e172412de5d0456dc00d2b34050aa0b683b5)
This reverts upstream commit 2f36db71009304b3f0b95afacd8eba1f9f046b87.
It fixed a local root exploit but also introduced a dependency on
the lower file system implementing an mmap operation just to open a file,
which is a bit of a heavy hammer. The right fix is to have mmap depend
on the existence of the mmap handler instead.
