lib/nvmf: implement WCTEMP and CCTEMP 



NVMe 1.3d, section 5.15.3, Figure 112, specifies for Identify
Controller fields WCTEMP and CCTEMP that:
"Implementations compliant to revision 1.2 or later of this
specification shall report a non-zero value in this field."

To conform to the NVMe specification, set WCTEMP to the
recommended value of 0157h (343 K, 70 deg C).
Set CCTEMP to a dummy value of 0175h (373 K, 100 deg C).
