There is no use case right now for kernel users to dynamically add/remove IAA compression modes; hence this commit deletes the symbol exports of add_iaa_compression_mode() and remove_iaa_compression_mode(). The only supported usage model of IAA compression modes is for the code to be statically linked during the iaa_crypto module build, e.g. iaa_crypto_comp_fixed.c, and for available modes to be registered when the first IAA device wq is probed.
