---------------------------

We use 'work_struct' private data to pass the pending events when we
schedule a 'delayed_work' in the following commit.
764cafd9875e ("pciehp: fix a race between pciehp and removing operations
by sysfs")
But workqueue framework will use this member, such as workqueue core
function 'set_work_pool_and_keep_pending()'. This patch add a new member
in 'struct delayed_work' and use this member to pass the pending events.
This patch also add more debug info.

operations by sysfs")
