Description of problem:

In some cases, an extra slash is prepended to a path name in the output of udevadm info.

Version-Release number of selected component (if applicable):

In Rawhide, 244. Also, on Fedora 30, 241. Also on Fedora 31, presumably on some version in between. Could not check Fedora 29. Not on RHEL8, 239.

How reproducible:

100%

Steps to Reproduce:
1. udevadm info --export-db. Pick an arbitrary device from the output.
2. udevadm info --path <pathname>.
3. Note that the paths have an extra '/' at the front (although this was not the case for the output of (1). The DEVPATH property is a good example.

Actual results:

Paths look like: E: DEVPATH=//devices/virtual/workqueue/writeback

Expected results:

Paths look like: E: DEVPATH=/devices/virtual/workqueue/writeback

Additional info:

None.
