[PATCH] powerpc/tau: Remove redundant parameter in alloc_workqueue() call

This avoids an (optional) compiler warning:

arch/powerpc/kernel/tau_6xx.c: In function 'TAU_init':
arch/powerpc/kernel/tau_6xx.c:204:30: error: too many arguments for format [-Werror=format-extra-args]
   tau_workq = alloc_workqueue("tau", WQ_UNBOUND, 1, 0);

Fixes: b1c6a0a10bfa ("powerpc/tau: Convert from timer to workqueue")
