init/calibrate.c: remove annoying printk

Remove calibrate_delay_direct()'s KERN_DEBUG printk related to bogomips
calculation as it appears when booting every core on setups with
'ignore_loglevel' which dmesg people scan for possible issues.  As the
message doesn't show very useful information to the widest audience of
kernel boot message gazers, it should be removed.

Introduced by commit d2b463135f84 ("init/calibrate.c: fix for critical
bogoMIPS intermittent calculation failure").
