Show only one error notification per inserted mulitpartitioned usb card.

Show only one error notification per inserted mulitpartitioned usb card.

iWe should use system path of the device that contains partitions block device, instead partitions system path as notifications identification path.

e.g.
/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0/host9/target9:0:0/9:0:0:0
instead of
/sys/devices/pci0000:00/0000:00:1d.7/usb1/1-6/1-6:1.0/host9/target9:0:0/9:0:0:0/block/sdb/sdb9

TEST=Manual on Cr48 (tried multiple-partitioned device with no good partitions, with one good-partition, device with one partition)

File chrome/browser/chromeos/extensions/file_browser_event_router.cc (right):

chrome/browser/chromeos/extensions/file_browser_event_router.cc:214:
disk->system_path().substr(0, disk->system_path().rfind("/block"));
/block feels bit too platform specific. i.e. new kernel might call this
differently

nothing better to search for here?

I am rewriting file browser notification code for m15 (should have cl up for
review tomorrow latest), and it should deal with both of these issues, but it
would be a bit painful to merge it into M14..
