Subject: [PATCH] svcrdma: delete double assignment

Delete successive assignments to the same location.

A simplified version of Coccinelle semantic match that finds this problem is as
follows:

// <smpl>
@@
expression i;
@@

*i = ...;
 i = ...;
// </smpl>

Signed-off-by: Himangi Saraogi <himangi774@...il.com>

Should the assignment be the maximum of the 2 values?
