fscrypt: move fscrypt_operations declaration to fscrypt_supp.h
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. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
