Thanks for looking into this, Sudip!  I will need to write up explicit
instructions, but the issue only shows up when you attempt to write to
an offset, which (I would presume) is why your test didn't produce any
issues.  My usecase is storing a DER encoded x509 certificate whose
footprint exceeds the TPM data bus size, thus requiring multiple
tpm2_nvwrite calls, with any call other than the initial, requiring the
--offset flag and the appropriate offset starting point.
