staging: comedi: Remove set but not used variable 'aref'
Fixes gcc '-Wunused-but-set-variable' warning:
drivers/staging/comedi/drivers/dt3000.c: In function dt3k_ai_insn_read:
drivers/staging/comedi/drivers/dt3000.c:511:27: warning: variable aref set but not used [-Wunused-but-set-variable]
It is not used since commit 2e310235ca8f ("staging:
comedi: dt3000: rename dt3k_ai_insn()")
