x86/RAS: Rename AMD MCE injector config item ... to be the same like the file name of injection module itself to avoid confusion when grepping. No functionality change.

tristate "Simple MCE injection interface for AMD processors"
x86/ras/mce_amd_inj: Inject bank 4 errors on the NBC Bank 4 MCEs are logged and reported only on the node base core (NBC) in a socket. Refer to the D18F3x44[NbMcaToMstCpuEn] field in Fam10h and later BKDGs. The node base core (NBC) is the lowest numbered core in the node. This patch ensures that we inject the error on the NBC for bank 4 errors. Otherwise, triggering #MC or APIC interrupts on a core which is not the NBC would not have any effect on the system, i.e. we would not see any relevant output on kernel logs for the error we just injected.

This is a simple debugfs interface to inject MCEs and test different
aspects of the MCE handling code.
WARNING: Do not even assume this interface is staying stable!
