[PATCH 2/3] btrfs-progs: output the correct path when fi-usage failed

[Gui Hecheng]

When we exec the following cmd:
        # btrfs file usage -t <path>  <-- an invalid path
output:
        # ERROR： can't access '-t'
should be:
        # ERROR: can't access 'path'

Just replace the static 'argv[1]' with 'argv[i]'.
