[PATCH v3 04/12] MdeModulePkg/SataControllerDxe: Fix up ASSERTS (Private != NULL)

["Pedro Falcato" <pedro.falcato@gmail.com>]

ASSERT (Private != NULL) (where Private = CR(...)) is ineffective as
CR(Ptr, Type, Member, Sig) either returns Ptr - offsetof(Type, Member),
or ASSERTS on the signature, so it's unlikely to ever return NULL
(must be passed a pointer = member's offset, or in this case, 0x4).

ASSERT on This != NULL instead.
