[PATCH 315/342] Staging: heci: do not print error when heci_bh_handler is already on workqueue

[Greg Kroah-Hartman]

From: Dongxiao Xu <dongxiao.xu at intel.com>

schedule_work returns 0, if the work is already on the work_queue, else
returns non-zero. Do not print error message if heci_bh_handlerwork was
already on queue.
