Increase the allowed number of retries
The max number of retries is the tpm2 code is completely inadequate
for the non-orderly shutdowns, it locks up the tpm for 1000 seconds
after three reboots.
This patch increases the number to 200 for the time being, this should
allow rigorous testing of other platform's features without repeatedly
locking up the TPM in the process.
On the long run a more comprehensive solution is needed, maybe
password attacks and non-orderly reboots need to be treated separately
with different lockout limits.
BRANCH=none
BUG=chrome-os-partner:55708
TEST=still to be completed: the TPM is not expected tolock up any more
after a few resets.
