Aravind Gopalakrishnan 284b965c14 x86/mce/AMD: Do not perform shared bank check for future processors 
Fam17h and above should not require a check to see if a bank is
shared or not. For shared banks, there will always be only one
core that has visibility over the MSRs and only that particular
core will be allowed to write to the MSRs.

Fix the code to return early if we have Scalable MCA support. No
change in functionality for earlier processors.
