northbridge/intel/nehalem: don't set FERR_CAPABILITY on BSP
This capability means: FERR messages are sent out on system detected an unmasked floating point x87 FPU error. Even though this capability is supported on nehalem it doesn't make sense to set it in early stage. This MSR has a core scope which results in an unsync MSR because it's not set on other cores than the BSP.
