x86: Use KERN_DEFAULT log-level in __show_regs()
Andrew Morton reported a strange looking kmemcheck warning:
WARNING: kmemcheck: Caught 32-bit read from uninitialized memory (ffff88004fba6c20)
0000000000000000310000000000000000000000000000002413000000c9ffff

The above printout is missing register dump completely. The
problem here is that the output comes from syslog which doesn't
show KERN_INFO log-level messages. We didn't see this before
because both of us were testing on 32-bit kernels which use the
_default_ log-level.
Fix that up by explicitly using KERN_DEFAULT log-level for
__show_regs() printks.
