MPILIB: add mpi_read_buf() and mpi_get_size() helpers
Added a mpi_read_buf() helper function to export MPI to a buf provided by the user, and a mpi_get_size() helper, that tells the user how big the buf is. Changed mpi_free to use kzfree instead of kfree because it is used to free crypto keys. Signed-off-by: Tadeusz Struk <tadeusz.struk@intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
