[v2,06/11] fscrypt: move fscrypt_operations declaration to fscrypt_supp.h

Commit Message

From: Eric Biggers <[e-mail]>

Filesystems now only define their fscrypt_operations when they are
compiled with encryption support, so move the fscrypt_operations
declaration from fscrypt.h to fscrypt_supp.h.
