scsi: hpsa: Fix allocation size for Scsi_Host private data

[ Upstream commit 504e2bed5d50610c1836046c0c195b0a6dba9c72 ]

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.
