[PATCH 01/10][next] scsi: aacraid: Replace one-element array with flexible-array member

Replace one-element array with flexible-array member in struct
aac_ciss_phys_luns_resp.

This results in no differences in binary output.

Issue found with the help of Coccinelle and audited and fixed,
manually.
