iscsi boot: fix iscsi_boot sysfs parsing

This fixes 2 bugs:
1. Some implementations will create boot sysfs dirs, but
not put anything in them or partially setup the boot sysfs
tree.

In those cases, if there are other boot dirs with valid info
then we do not want to fail the entire operation.

2. The iscsi_boot dir was not getting processed correctly,
because of a missing "/" in the path name.
