zfcp: correctly set this_id for hosts

This patch is for 2.6.16.

It fixes a bug in zfcp which provokes a race in scsi_scan.c. Finally this can lead to an Oops like:

kernel BUG at fs/sysfs/symlink.c:87!
...

sysfs_create_link+0x16e/0x1c4
class_device_add+0x194/0x3b8
attribute_container_add_class_device+0x26/0x50
transport_add_class_device+0x34/0x6c
attribute_container_device_trigger+0x170/0x174
scsi_alloc_target+0x22c/0x360
__scsi_add_device+0x3a/0x148
scsi_add_device+0x2c/0x54
zfcp_erp_thread+0xb90/0x152c
kernel_thread_starter+0x6/0xc

Please apply. Thanks!

Regards,

Andreas

zfcp: correctly set this_id for hosts

Correctly set this_id for the host. Otherwise we provoke a race between scsi_target_reap_work and concurrent scsi_add_device.
