Fix a crash caused by a double put on the node when the driver
completed an ACC for an unsolicted abort on the same node.  The
second put was executed by lpfc_nlp_not_used and is wrong because
the completion routine executes the nlp_put when the iocbq was
released.  Additionally, the driver is issuing a LOGO then
immediately calls lpfc_nlp_set_state to put the node into NPR.
This call does nothing.

Remove the lpfc_nlp_not_used call and additional set_state in the
  completion routine.
Remove the lpfc_nlp_set_state post issue_logo.  Isn't necessary.
