sysfs: Update the name hash when renaming sysfs entries
This fixes a bug introduced with sysfs name hashes where renaming a network device appears to succeed but silently makes the sysfs files for that network device inaccessible. In at least one configuration this bug has stopped networking from coming up during boot. Signed-off-by: Eric W.
