NFC is using a number of custom ordered workqueues w/ WQ_MEM_RECLAIM.
WQ_MEM_RECLAIM is unnecessary unless NFC is gonna be used as transport
for storage device, and all use cases match one work item to one
ordered workqueue - IOW, there's no actual ordering going on at all
and using system_nrt_wq gives the same behavior.

There's nothing to be gained by using custom workqueues.  Use
system_nrt_wq instead and drop all the custom ones.

During NFC-DEP target activation, store the remote
general bytes to be used later in dep_link_up.
When dep_link_up is called, activate the NFC-DEP target,
and forward the remote general bytes.
When dep_link_down is called, deactivate the target.

It is a frequent mistake to confuse the netlink port identifier with a
process identifier.  Try to reduce this confusion by renaming fields
that hold port identifiers portid instead of pid.

I have carefully avoided changing the structures exported to
userspace to avoid changing the userspace API.

I have successfully built an allyesconfig kernel with this change.

This API should be used by drivers, HCI, SHDLC or NCI stacks to report an
unrecoverable error.

This routine will be called by drivers whenever they receive data in target
mode. This should be unexpected events and as such should be handled by a
standalone API (i.e. not as a callback pointer from an existing API).

And rename the initiator mode data exchange ops for consistency sake.

Userspace gets a netlink event upon target mode activation.
The LLCP layer is also signaled when we get an ATR_REQ in order to get
the remote general bytes.
