Re: kern/52796: repeated modload panics netbsd-7

[Paul Goyette <paul%whooppee.com@localhost>]

The "symbol redefined" error messages you see on NetBSD-8 are actually a 
result of the fix for this PR!  Prior to sys/kern/subr_kobj.c rev 1.52, 
the duplicate symbols were not detected, the module was loaded, and its 
initialization routine was called.  All sorts of bad stuff can happen if 
the module/driver is already initialized.  :)

With rev 1.52 (the fix committed for PR kern/45125), duplicate symbols 
are detected, and the module load fails to complete.  As a result, 
initialization code does not get called so all the bad-stuff(tm) goes 
away.

I will request that rev 1.52 be pulled-up to netbsd-7 branch.
