soundwire: stream: Remove unneeded checks for NULL bus

Version of the code prior to commit d014688eb373 ("soundwire: stream:
remove bus->dev from logs on multiple buses"), used bus->dev in the
error message after do_bank_switch, this necessitated some checking to
ensure the bus pointer was valid. As the code no longer uses bus->dev
said checking is now redundant, so remove it.
