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 arrays with flexible-array
members in a couple of structures, and refactor the rest of the code,
accordingly.
This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines
on memcpy().
This results in no differences in binary output.
