scsi: pm8001: Remove PM8001_READ_VPD 

Remove the macro PM8001_READ_VPD used to define if a controller WWN should
be retrieved from the device. Instead, define the better named boolean
module parameter "read_wwn" to control this.

The code to set a fixed address for a phy device address when read_wwn is
set to false is simplified and fixed to avoid sparse warnings.
