Synopsis: [pmap] pmap.c panic message references a sysctl that doesn't exist

State-Changed-Why: 
The message is correct.  However, it is *NOT* a sysctl, rather it is a
tunable that can be set in /boot/loader.conf eg:

	vm.pmap.shpgperproc=1000

Making this a sysctl, with the ability to dynamically change it whilst
the system is running would be Exceptionally Hard[tm].

One could possibly make a case for providing a read-only sysctl, though
it is likely to be of very limited use, since pv exhaustion is not by
any means a typical occurance.

Responsible-Changed-Why: 
Since I provided the specific "fix" (in terms of an appropriate panic,
rather than letting the kernel wander off into la-la land as was the
case previously), I'll assume (some of ;) the responsibility...
