Protected entire epioctl routine with splimp(). In this case, it is better

form to do this than it is relying on individual subroutines (the logic
in epioctl is itself very minimal). Ideally, unnecessary splimp()'s should
now be removed if they exist; I'll leave this for a later date (a complete
code review of the driver needs to be done). Fixes a bug I noticed that
would show up when ifconfig'ing the interface down.
