RFC: Pass TRIM through GELI

[Matthew D. Fuller]

On Mon, Mar 16, 2015 at 05:13:23AM -0500 I heard the voice of
Matthew D. Fuller, and lo! it spake thus:

As a side note, this seems to turn from "darn" to "panic" because in
g_eli_read_metadata(), it doesn't check the return from
eli_metadata_decode(), so it doesn't notice the EINVAL and happily
reports back success without ever having touched the md   :(
