Commit 3a878c430fd6 ("tty: serial: msm: Add TX DMA support") regression.
The calculation of tx_count was moved from the old msm_handle_tx(),
now renamed msm_handle_tx_pio(), to the new msm_handle_tx(). The
move left out one size test.
The regression seen on the qcom-apq8074-dragonboard is dropped
characters and corrupted characters (values greater than 0x7f)
when DMA is not enabled.
