hw/intc/arm_gicv3: Check for !MEMTX_OK instead of MEMTX_ERROR 

Quoting Peter Maydell:

 "These MEMTX_* aren't from the memory transaction
  API functions; they're just being used by gicd_readl() and
  friends as a way to indicate a success/failure so that the
  actual MemoryRegionOps read/write fns like gicv3_dist_read()
  can log a guest error."

We are going to introduce more MemTxResult bits, so it is
safer to check for !MEMTX_OK rather than MEMTX_ERROR.
