[SCSI] pm8001: introduce missing kfree

Error handling code following a kmalloc should free the allocated data.

The semantic match that finds the problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@r exists@
local idexpression x;
expression E;
identifier f,f1;
position p1,p2;

x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...);
<... when != x

     when != (x) == 0
     when != (x) != 0

 (x->f1 == NULL || ...)

 f(...,x->f1,...)
