Subject: [PATCH 2/3][next] scsi: smartpqi: Replace one-element arrays with
 flexible-array members

One-element arrays are deprecated, and we are replacing them with flexible
array members instead. So, replace one-element array with flexible-array
member in structures report_phys_lun_8byte_wwid_list and
report_phys_lun_16byte_wwid_list.

This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy().
