Douglas Anderson 55a7e23f46 kdb: Fix "btc <cpu>" crash if the CPU didn't round up
I noticed that when I did "btc <cpu>" and the CPU I passed in hadn't
rounded up that I'd crash.  I was going to copy the same fix from
commit 162bc7f5af ("kdb: Don't back trace on a cpu that didn't round
up") into the "not all the CPUs" case, but decided it'd be better to
clean things up a little bit.

This consolidates the two code paths.  It is _slightly_ wasteful in in
that the checks for "cpu" being too small or being offline isn't
really needed when we're iterating over all online CPUs, but that
really shouldn't hurt.  Better to have the same code path.

While at it, eliminate at least one slightly ugly (and totally
needless) recursive use of kdb_parse().
