        src/sys/kern: kern_module.c

Log Message:
When loading a kernel, test if it's already loaded before authorizing.
This allows us to return EEXIST instead of EPERM for higher secure levels.

My use case was to stop npfctl complaining that it could not load bpfjit
on ERLITE when it was compiled into the kernel.
It then went on to complain that NPF performance would be de-graded,
but this is clearly not the case.
