As of now, crypto_kpp_maxsize() can not be reached without successfully
setting the key for the transformation. kpp algorithm implementations
check if the key was set and then return the output buffer size
required for the given key.
Change the return type to unsigned int and always assume that this
function is called after a successful setkey of the transformation.
kpp algorithm implementations will remove the check if key is not NULL
and directly return the max size.
