Subject: [PATCH] scsi: hpsa: Fix allocation size for Scsi_Host private data

struct Scsi_Host private data contains pointer to struct ctlr_info.

Restore allocation of only 8 bytes to store pointer in struct Scsi_Host
 private data area.

Found by Linux Verification Center (linuxtesting.org) with SVACE.

Fixes: bbbd25499100 ("scsi: hpsa: Fix allocation size for scsi_host_alloc()")
