From: Eric Biggers <ebiggers@xxxxxxxxxx>
Filesystems only ever access 'struct fscrypt_ctx' through fscrypt
functions. But when a filesystem is built without encryption support,
these functions are all stubbed out, so the declaration of fscrypt_ctx
is unneeded. Therefore, move it from fscrypt.h to fscrypt_supp.h.
