Dave Allan b31ef77313 nodedev: Fix sysfs paths for vport operations
Some kernels, such as the one used in RHEL-5, have vport_create and
vport_delete operation files in /sys/class/scsi_host/hostN directory
instead of /sys/class/fc_host/hostN. Let's check both paths for
compatibility reasons.

This also removes unnecessary '/' characters from sysfs paths containing
LINUX_SYSFS_FC_HOST_PREFIX.
