powerpc/eeh: Fix pseries_eeh_configure_bridge()

Browse source

If a device is hot unplgged during EEH recovery, it's possible for the
RTAS call to ibm,configure-pe in pseries_eeh_configure() to return
parameter error (-3), however negative return values are not checked
for and this leads to an infinite loop.

Fix this by correctly bailing out on negative values.
