Fix BDF search by matching a single character for function

[cliffbird]

The first device underneath a switch does not obtain all its status information because the glob search matches more than one entry (line 429). For example:

$ ls -l /sys/devices/pci0000:00/0000:00:01.1/0000:01:00.0/
total 0
drwxr-xr-x  3 root root    0 Oct  3 21:59 0000:01:00.0:pcie102  <-----
drwxr-xr-x 12 root root    0 Oct  3 21:59 0000:02:00.0
drwxr-xr-x 12 root root    0 Oct  3 21:59 0000:02:01.0
drwxr-xr-x 12 root root    0 Oct  3 21:59 0000:02:02.0
drwxr-xr-x 12 root root    0 Oct  3 21:59 0000:02:03.0
drwxr-xr-x 10 root root    0 Oct  3 21:59 0000:02:04.0
drwxr-xr-x 11 root root    0 Oct  3 21:59 0000:02:05.0

The glob search will return both 0000:01:00.0:pcie102 and 0000:02:00.0 therefore pci_bdf for the device is not populated (see line 430).

Oh, hmm, that's strange that that device is there. But it looks like your patch should work around that issue fine.

Thanks!
