interrupts: Fix parsing of users field

It is the last field, in CSV format, and that was what was being parsed,
but in a convoluted way, fixing it also simplified it.

Buggy:

  [root@zoo ~]# tuna -Q
     # users            affinity
     0 2-edge      timer  0,1,2,3
     8 8-edge      rtc0  0,1,2,3
     9 9-fasteoi   acpi  0,1,2,3
    17 17-fasteoi   brcmsmac  0,1,2,3
    22 22-fasteoi   ehci_hcd:usb4  0,1,2,3
    23 23-fasteoi   ehci_hcd:usb3  0,1,2,3
    26 2146304-edge      pciehp  0,1,2,3
    27 2162688-edge      pciehp  0,1,2,3
    28 2179072-edge      pciehp  0,1,2,3
    29 2195456-edge      pciehp  0,1,2,3
    30 512000-edge      0000:00:1f.2  0,1,2,3
    31 327680-edge      xhci_hcd  0,1,2,3
    32 32768-edge      i915  0,1,2,3
    33 360448-edge      mei_me  0,1,2,3
    34 2621440-edge      thunderbolt  0,1,2,3
    35 442368-edge      snd_hda_intel  0,1,2,3
  [root@zoo ~]#

Fixed:
