[PATCH] drm/amdkfd: Fix wrong usage of INIT_WORK()

[Yuan Can]

In kfd_procfs_show(), the sdma_activity_work_handler is a local variable
and the sdma_activity_work_handler.sdma_activity_work should initialize
with INIT_WORK_ONSTACK() instead of INIT_WORK().

Fixes: 32cb59f31362 ("drm/amdkfd: Track SDMA utilization per process")
