Commit e2fb992d82c6 ("tpm: add retry logic") introduced a new loop to
handle the TPM2_RC_RETRY error. The loop retries the command after
sleeping for the specified time, which is incremented exponentially in
every iteration.
Unfortunately, the loop doubles the time before sleeping, causing the
initial sleep to be doubled. This patch fixes the initial sleep time.
