Subject: [PATCH] ATM: Fix wrong usage of INIT_WORK

From: Wang Shaoyan <wangshaoyan.pt@...bao.com>

If we define FILL_RX_POOLS_IN_BH, the compiler will report error such as
  drivers/atm/ambassador.c:2159:64: error: macro "INIT_WORK" passed 3 arguments, but takes just 2
because the function INIT_WORK() don't accept "data" now, it only has
two arguments, so use the right way to initialise work queue.
