  To: linux-rdma-u79uwXL29TY76Z2rM5mHXA, dledford-H+wXaHxf7aLQT0dZR+AlfA
  Cc: pandit.parav-Re5JQEeQqe8AvxtiuMwx3w

1. Replaced printk with appropriate pr_warn, pr_err, pr_info.
2. Removed unnecessary prints around memory allocation failure
which are not required, as reported by the checkpatch script.
