ceph: move crypt info pointer to fs-specific part of inode
Move the fscrypt_inode_info pointer into the filesystem-specific part of
the inode by adding the field ceph_inode_info::i_crypt_info and
configuring fscrypt_operations::inode_info_offs accordingly.
This is a prerequisite for a later commit that removes
inode::i_crypt_info, saving memory and improving cache efficiency with
filesystems that don't support fscrypt.
