xprtrdma: drop double zeroing

Browse Source 
sg_init_table zeroes its first argument, so the allocation of that argument

the semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)

// <smpl>

x =
- kcalloc
+ kmalloc_array
  (n,sizeof(*x),flags)
...
sg_init_table(x,n)
// </smpl>
