Dan Carpenter aecf64a4ad kdb: do a sanity check on the cpu in kdb_per_cpu() ...

[ Upstream commit b586627e10 ]

The "whichcpu" comes from argv[3].  The cpu_online() macro looks up the
cpu in a bitmap of online cpus, but if the value is too high then it
could read beyond the end of the bitmap and possibly Oops.

Fixes: 5d5314d679 ("kdb: core for kgdb back end (1 of 2)")
