[PATCH] Add host open devicename check

grub-emu ls command does not list any partitions.

Device scan in grub_disk_open() stops early because grub_host_open() 
returns success on all device names.

	* disk/host.c (grub_host_open): Add check for "host". This fixes
	the problem that grub-emu does not find partitions.
