[patch] arm64: set correct length of device path end entry

From: Leif Lindholm
Subject: [patch] arm64: set correct length of device path end entry
Date: Tue, 7 Jan 2014 17:06:08 +0000
User-agent: Mutt/1.5.21 (2010-09-15)

The length of the Device Path End entry in the grub_linux_boot()
funtcion is incorrectly set to 0. This triggers an assert failure
in debug builds of Tianocore.

The correct length is 4 bytes (1 byte type, 1 byte subtype,
2 bytes length).

Reported-by: Mark Salter <address@hidden>
