exportfs: make ->encode_fh() a mandatory method for NFS export
Rename the default helper for encoding FILEID_INO32_GEN* file handles to
generic_encode_ino32_fh() and convert the filesystems that used the
default implementation to use the generic helper explicitly.
After this change, exportfs_encode_inode_fh() no longer has a default
implementation to encode FILEID_INO32_GEN* file handles.
This is a step towards allowing filesystems to encode non-decodeable
file handles for fanotify without having to implement any
export_operations.
