asomers 3ab78c10af geli: use unmapped I/O 
Use unmapped I/O for geli. Unlike most geom providers, geli needs to
manipulate data on every read or write. Previously it would always map bios.

On my 16-core, dual socket server using geli atop md(4) devices, with 512B
sectors, this change increases geli IOPs by about 3x.

Note that geli still can't use unmapped I/O when data integrity verification
is enabled (but it could, with a little more work).  And it can't use
unmapped I/O in combination with ZFS, because ZFS uses mapped bios.
