Ian Jackson 77e856d7f3 Serial: Do not read IIR in serial8250_start_tx when UART_BUG_TXEN ...

commit 68cb4f8e246bbbc649980be0628cae9265870a91 upstream.

Do not read IIR in serial8250_start_tx when UART_BUG_TXEN

Reading the IIR clears some oustanding interrupts so it is not safe.
Instead, simply transmit immediately if the buffer is empty without
regard to IIR.
