scsi: hpsa: Enlarge controller and IRQ name buffers

Browse Source 
hpsa formats the controller name into h->devname[8] and derives
interrupt names from it in h->intrname[][16]. Once host_no reaches four
digits, "hpsa%d" no longer fits in devname, and the derived IRQ names
can then overrun the interrupt-name buffers as well.

The previous fix switched these builders to bounded formatting, but that
would truncate user-visible controller and IRQ names. Keep the existing
names intact instead by enlarging the fixed buffers to cover the current
formatted strings.

Fixes: 2946e82bdd ("hpsa: use scsi host_no as hpsa controller number")
Fixes: 8b47004a55 ("hpsa: add interrupt number to /proc/interrupts interrupt name")
