tpm: remove @space from tpm_transmit()
Remove @space from tpm_transmit() API` in order to completely remove the bound between low-level transmission functionality and TPM spaces. The only real dependency existing is the amount of data saved before trying to send a command to the TPM. It doesn't really matter if we save always a bit more than needed so this commit changes the amount saved always to be the size of the TPM header and three handles.
