Add an inode_info_offs field to struct fscrypt_operations, and update fs/crypto/ to support it. When set to a nonzero value, it specifies the offset to the fscrypt_inode_info pointer within the filesystem-specific part of the inode structure, to be used instead of inode::i_crypt_info. Since this makes inode::i_crypt_info no longer necessarily used, update comments that mentioned it. 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.
