PCI hotplug: fix logic in Compaq hotplug controller bus speed setup 

The pattern !E && !E->fld is nonsensical.  The patch below updates this
according to the assumption that && should be ||.  But perhaps another
solution was intended.

The semantic patch that makes this change is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@disable and_comm@
expression E;
identifier fld;
@@

- !E && !E->fld
+ !E || !E->fld
// </smpl>
