[Xen-devel] [RFC PATCH 10/84] x86/mm: change pl2e to l2t in virt_to_xen_l2e

[<hongyax@xxxxxxxxxx>]

From: Wei Liu <wei.liu2@xxxxxxxxxx>

We will need to have a variable named pl2e when we rewrite
virt_to_xen_l2e. Change pl2e to l2t to reflect better its purpose.
This will make reviewing later patch easier.

No functional change.
