Avoid memory allocations when the given address is already 16 bytes aligned.
Such an address can be used directly in padlock's AES.
This improves speed of geli(8) significantly:
# sysctl kern.geom.zero.clear=0
# geli onetime -s 4096 gzero
# dd if=/dev/gzero.eli of=/dev/null bs=1m count=1000
Before: 113MB/s
After: 203MB/s
BTW. If sector size is set to 128kB, I can read at 276MB/s :)
