  MFC r234507:
  
  Fix the following compilation warnings in sys/contrib/rdma/rdma_cma.c:
  
    sys/contrib/rdma/rdma_cma.c:1259:8: error: case value not in enumerated type 'enum iw_cm_event_status' [-Werror,-Wswitch]
  	    case ECONNRESET:
  		 ^
    @/sys/errno.h:118:20: note: expanded from macro 'ECONNRESET'
    #define ECONNRESET      54              /* Connection reset by peer */
  		    ^
    sys/contrib/rdma/rdma_cma.c:1263:8: error: case value not in enumerated type 'enum iw_cm_event_status' [-Werror,-Wswitch]
  	    case ETIMEDOUT:
  		 ^
    @/sys/errno.h:124:19: note: expanded from macro 'ETIMEDOUT'
    #define ETIMEDOUT       60              /* Operation timed out */
  		    ^
    sys/contrib/rdma/rdma_cma.c:1260:8: error: case value not in enumerated type 'enum iw_cm_event_status' [-Werror,-Wswitch]
  	    case ECONNREFUSED:
  		 ^
    @/sys/errno.h:125:22: note: expanded from macro 'ECONNREFUSED'
    #define ECONNREFUSED    61              /* Connection refused */
  		    ^
  
  This is because the switch uses iw_cm_event::status, which is an enum
  iw_cm_event_status, while ECONNRESET, ETIMEDOUT and ECONNREFUSED are
  just plain defines from errno.h.
  
  It looks like there is only one use of any of the enumeration values of
  iw_cm_event_status, in:
  
    sys/contrib/rdma/rdma_iwcm.c:       if (iw_event->status == IW_CM_EVENT_STATUS_ACCEPTED) {
  
  So messing around with the enum definitions to fix the warning seems too
  disruptive; the simplest fix is to cast the argument of the switch to
  int.
