Subject: scsi: hpsa: Fix allocation size for scsi_host_alloc()
Git-commit: bbbd25499100c810ceaf5193c3cfcab9f7402a33
Patch-mainline: v6.2-rc6
References: git-fixes

The 'h' is a pointer to struct ctlr_info, so it's just 4 or 8 bytes, while
the structure itself is much bigger.

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

Fixes: edd163687ea5 ("hpsa: add driver for HP Smart Array controllers.")
