[PATCH] phy: can-transceiver: Drop unnecessary "mux-states" property presence check

["Rob Herring (Arm)" <robh@kernel.org>]

It doesn't matter whether "mux-states" is not present or there is some
other issue parsing it causing an error. Drop the presence check and
rework the error handling to ignore anything other than deferred probe.
