[norman shen]

scsi disk path name change on arm 64 device, so https://github.com/openstack/os-brick/blob/e883a6544466c37e8a3639751351cbceec404ef0/os_brick/initiator/connectors/fibre_channel.py#L283 this code is not working.

the new name looks like this (notice the new prefix)

    prepend platform info to by-path string

    By default, udev will set device by-path name to its ID_PATH.

    Looking at [1], most of the time, current code works,
    but when system uses platform, then disk name will be prefixed by
    'platform-xxxxx'.
