[ Upstream commit bbbd25499100c810ceaf5193c3cfcab9f7402a33 ]
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.")
