Log Message:
swstrategy: reject non page aligned i/o explicitly

our swap offset calculation logic assumes page aligned i/o.
non aligned requests from /dev/drum silently go to a wrong block.
it has always been this way since the initial uvm import in 1998.
this commit fixes it by simply rejecting non aligned requests.
note: requests from swap and libkvm are always page aligned.
