[patch 21/26] drivers/scsi/bfa/bfad_im.c: eliminate useless code

[akpm]

From: Julia Lawall <julia@diku.dk>

The variable bfa_itnim is initialized twice to the same (side effect-free)
expression.  Drop one initialization.

A simplified version of the semantic match that finds this problem is:
(http://coccinelle.lip6.fr/)

// <smpl>
@forall@
idexpression *x;
identifier f!=ERR_PTR;
@@

x = f(...)
... when != x
(
x = f(...,<+...x...+>,...)
|
* x = f(...)
)
// </smpl>
