[PATCH] x86: Don't print number of MCE banks for every CPU

[Roland Dreier <rdreier@cisco.com>]

The MCE initialization code explicitly says it doesn't handle asymmetric
configurations where different CPUs support different numbers of MCE
banks, and it prints a big warning in that case.  Therefore, printing
the "mce: CPU supports <x> MCE banks" message into the kernel log for
every CPU is pure redundancy that clutters the log significantly for
systems with lots of CPUs.
