On the msm8998 mtp, the response to the baudrate change command is never
received. On the Lenovo Miix 630, the response to the baudrate change
command is corrupted - "Frame reassembly failed (-84)".
Adding a 50ms delay before re-enabling flow to receive the baudrate change
command response from the wcn3990 addesses both issues, and allows
bluetooth to become functional.
