nb/amd/mct_ddr3: Run fence training on each node after memory clock change 

The BKDG requires phy fences to be re-trained after a memory clock change.
Memory training on the ASUS KGPE-D16 and KCMA-D8 somehow "mostly" worked
 -- without actually following this requirement -- !

Fix the single typo that caused several weeks of delay in putting
servers with Kingston RAM (and others) into production...

Tested-On: ASUS KGPE-D16
Config-CPU: 1x Opteron 6262HE
Config-RAM: 4x Crucial 36KSF1G72PZ-1G6M1
