Subject: [PATCH 1/3] tpm2: Reset TPM2B buffer sizes after test fails for valid
buffer size
Reset the buffer size indicator in a TPM2B type of buffer after it failed
the test for the maximum buffer size it allows. This prevents having bad
buffer sizes in memory that can come to haunt us when writing the volatile
state for example.

Subject: [PATCH 2/3] tpm2: Add maxSize parameter to TPM2B_Marshal for sanity
checks
Add maxSize parameter to TPM2B_Marshal and assert on it checking
the size of the data intended to be marshaled versus the maximum
buffer size.
