Subject: [PATCH 1/1] fcoe-utils: Fix get_ctlr_num() for large ctlr_* indices

Each creation of a FCoE device increases counter which is used as a suffix
in a FCoE device name in sysfs (i.e. /sys/bus/fcoe/devices/ctlr_1).
Once this counter reaches the value of two digits (10 and larger),
get_ctlr_num() stopped working properly and a command like `fcoeadm -i`
which depends on get_ctlr_num() call doesn't show anything.
This patch solves this problem.
