Ricardo Schwarzmeier 36a11029b0 tpm: Return the actual size when receiving an unsupported command 
The userpace expects to read the number of bytes stated in the header.
Returning the size of the buffer instead would be unexpected.

Cc: stable@vger.kernel.org
Fixes: 095531f891 ("tpm: return a TPM_RC_COMMAND_CODE response if command is not implemented")
