mptfusion: make adapter prod_name[] a pointer
The struct _MPT_ADAPTER doesn't need a full copy of the product string,
so prod_name can point to the string literal storage that the driver
already provides.
Avoids the following smatch warning:
drivers/message/fusion/mptbase.c:2858 MptDisplayIocCapabilities()
warn: this array is probably non-NULL. 'ioc->prod_name'
