ucd_disable_vcs: Don't wait for bound device link to appear
The driver is bound at boot, so if the driver isn't bound then it won't
be in the future, unless explicitly bound from userspace.
A previous commit (8ca6161774d, "meta-witherspoon: vcs-control: Add retries and
journal entries") introduced retries for both unbind/bind operations of
the UCD9000 driver for the UCD90160.
Don't wait for a symlink to appear if it isn't present.
