Tadeusz Struk 18c3955323 tpm: Handle negative priv->response_len in tpm_common_read() ...

commit a430e67d9a upstream.

The priv->response_length can hold the size of an response or an negative
error code, and the tpm_common_read() needs to handle both cases correctly.
Changed the type of response_length to signed and accounted for negative
value in tpm_common_read().
