src/cpu/x86/smm: remove debug message; not thread safe

This patch removes a call to console_init() and debug print message since
the code is not thread safe. This prevents system hangs (soft hangs)
while in SMM if user drops in a new SOC with more cores or another
socket or as a result of bad configuration. Console is already
initialized after the lock has been acquired so this does not affect any
other functionality.

Tested on DeltaLake mainboard with SMM enabled and 52 CPU threads.
