ecryptfs: fix broken build

Stephen Rothwell reports that the vfs merge broke the build of ecryptfs.
The breakage comes from commit 66cb76666d69 ("sanitize ecryptfs
->mount()") which was obviously not even build tested. Tssk, tssk, Al.

This is the minimal build fixup for the situation, although I don't have
a filesystem to actually test it with.
