[Toybox] [PATCH] lspci: fix output of device info with new pci.ids

[Isaac Dunham]

lspci: fix output of device info with new pci.ids

With a new pci id database, available at
http://pciids.sourceforge.net/v2.2/pci.ids.bz2
(or also in gzip/uncompressed format),
lspci was frequently ignoring the device.
The fix was to explicitly ignore comments.

--
Reading lspci.c again, memset(toybuf, 0, 4096); is needed because it 
initializes vname/devname to an empty state; removing that line would 
result in garbage text output/repetition of the wrong vendor and device
information.

HTH,
Isaac Dunham
