Alok Prasad 0191c271de RDMA/qedr: iWARP invalid(zero) doorbell address fix 
This patch fixes issue introduced by a previous commit where iWARP
doorbell address wasn't initialized, causing call trace when any RDMA
application wants to use this interface:

  Illegal doorbell address: 0000000000000000. Legal range for doorbell addresses is [0000000011431e08..00000000ec3799d3]
