[PATCH 2/2] Char: mxser, use THRE for ASPP_OQUEUE ioctl

[Jiri Slaby]

In moxa specific ASPP_OQUEUE ioctl command, they apparently want
only know whether there is space in transmitter hold register.

So switch UART_LSR_TEMT to UART_LSR_THRE in that specific case
according to the change in 1.14 moxa drivers.
