Log Message:
-----------
SecurityPkg/Tpm2CommandLib: Update not found RC for Public NV Read
Currently a EFI_DEVICE_ERROR is returned if `TPM_RC_HANDLE` is the
return code from a TPM2_NV_ReadPublic command. However, in the TCG
TPM Library Part 3: Commands specification, `TPM_RC_HANDLE` is a
return code if:
1. An Index does not exist that corresponds to the handle
(TPM_RC_HANDLE)
2. The hierarchy associated with the existing NV Index is not
enabled (TPM_RC_HANDLE)
Therefore, return EFI_NOT_FOUND in this case, since that more
precisely allows a caller to identify this condition and act on
it as opposed to a more generic device error.
