[SCSI] pm8001: drop redundant memset

Browse source 
The region set by the call to memset is immediately overwritten by the
subsequent call to memcpy.

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

// <smpl>

expression e1,e2,e3,e4;
@@

- memset(e1,e2,e3);
  memcpy(e1,e4,e3);
// </smpl>
