Use the marshalled size of an OBJECT to check whether it still fits into NVRAM rather than using the size of the OBJECT (sizeof(obj), which is much bigger. Using the marshalled size also handles the case where the OBJECT is still copied into NVRAM using memcpy for the NULL profile case of libtpms v0.9. This should have been converted once NvObjectToBuffer() was started to be called there. Signed-off-by: Stefan Berger <stefanb@linux.ibm.com>
