[PATCH-for-5.0] gdbstub: Use correct address space with Qqemu.PhyMemMode packet

[Philippe Mathieu-Daudé]

Since commit 3f940dc98, we added support for vAttach packet
to select a particular thread/cpu/core. However when using
the GDB physical memory mode, it is not clear which CPU
address space is used.
Since the CPU address space is stored in CPUState::as, use
address_space_rw() instead of cpu_physical_memory_rw().
