Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/vc04_services/bcm2835-audio/bcm2835-vchiq.c: In function audio_vchi_callback:
drivers/staging/vc04_services/bcm2835-audio/bcm2835-vchiq.c:99:6: warning: variable status set but not used [-Wunused-but-set-variable]

It is not used since commit 23b028c871e1 ("staging:
bcm2835-audio: initial staging submission")
