lszfcp: allow to show zfcp_units without associated SCSI device

Browse Source 
Useful to detect configuration errors and FCP LUN typos.

Example:

$ lszfcp -De
0.0.3c80/0x500507630313d327/0xffffffffffffffff - failed

$ lszfcp -DeV
/sys/devices/css0/0.0.0222/0.0.3c80/0x500507630313d327/0xffffffffffffffff failed
-

$ lszfcp -Deam
0.0.3c80/0x500507630313d327/0xffffffffffffffff - failed
Class = "zfcp_unit"
    access_denied       = "0"
    access_readonly     = "0"
    access_shared       = "0"
    failed              = "1"
    in_recovery         = "0"
    status              = "0x00000000"
