MdeModulePkg: AcpiTableDxe: fix VS2008 build by merging adjacent if blocks 

The assignment of CurrentRsdtEntry and its subsequent dereference are
subject to the same condition, but for some reason, VS2008 does not see
that and warns about the dereference possibly involving an uninitialized
pointer. Since the single statememt between the blocks is unrelated, we
can just move it and merge the two conditional blocks together.
