connect_work and err_work will be reused by nvme-tcp so
share those in nvme_ctrl for rdma and fc to share.

As said before when you sent this invididually:  I'd rather not move
struct members to the common struture until we actually start using
it there.  So for now please add it to the containing TCP-specific
structure, although I'm looking forward to actually see code around
it consolidated eventually.

FFFine....
