rtl8139: do not assume TxStatus[] and TxAddr[] are adjacent
Commit afe0a595356192d5f79703cf6462fcc112df007c ("rtl8139: support byte read to TxStatus registers") reused rtl8139_TxStatus_read() for reading TxAddr registers. It relies on the fact that TxStatus[] and TxAddr[] are adjacent. This causes a gcc warning because the compiler can detect that array access is out-of-bounds: hw/rtl8139.c:2501:27: error: array subscript is above array bounds [-Werror=array-bounds] This patch refactors the function so that we don't rely on out-of-bounds accesses.
