scsi: hpsa: Make buff allocation type unsigned

In preparation for converting the kmalloc family of allocators to the
type-aware kmalloc_obj family, we need to make sure that the returned type
from the allocation matches the type of the variable being assigned. (The
kmalloc family returns "void *", which can be implicitly cast to any
pointer type.)

The assigned type is "unsigned char **", but the converted allocation type
would be "char **", whose elements point to a character type of a different
signedness, so the two pointer types are not compatible. Take the size from
the assignment target instead. No change in allocation size results.

Build tested ARCH=x86_64 allmodconfig with GCC 16.2.0:
drivers/scsi/hpsa.o
