nvme-rdma: fix sysfs invoked reset_ctrl error flow
When reset_controller that is invoked by sysfs fails,
it enters an error flow which practically removes the
nvme ctrl entirely (similar to delete_ctrl flow). It
causes the system to hang, since a sysfs attribute cannot
be unregistered by one of its own methods.
This can be fixed by calling delete_ctrl as a work rather
than sequential code. In addition, it should give the ctrl
a chance to recover using reconnection mechanism (consistant
with FC reset_ctrl error flow). Also, while we're here, return
suitable errno in case the reset ended with non live ctrl.
