security/tpm/tcg-2.0: Handle TPM_RC_NV_RANGE return code

As per the TPM spec, if offset and the size field of data add to a value
that is greater than the dataSize field of the NV Index referenced by
nvIndex, the TPM shall return an error (TPM_RC_NV_RANGE). Handle the TPM
error and map it to an appropriate vboot error.

BUG=None
TEST=Build and boot to OS in Guybrush.
