Claire Chang bbe6d14a98 Bluetooth: hci_uart: Fix a race for write_work scheduling 
[ Upstream commit afe0b1c86458f121b085271e4f3034017a90d4a3 ]

In hci_uart_write_work, there is a loop/goto checking the value of
HCI_UART_TX_WAKEUP. If HCI_UART_TX_WAKEUP is set again, it keeps trying
hci_uart_dequeue; otherwise, it clears HCI_UART_SENDING and returns.

In hci_uart_tx_wakeup, if HCI_UART_SENDING is already set, it sets
HCI_UART_TX_WAKEUP, skips schedule_work and assumes the running/pending
hci_uart_write_work worker will do hci_uart_dequeue properly.

However, if the HCI_UART_SENDING check in hci_uart_tx_wakeup is done after
the loop breaks, but before HCI_UART_SENDING is cleared in
hci_uart_write_work, the schedule_work is skipped incorrectly.

Fix this race by changing the order of HCI_UART_SENDING and
HCI_UART_TX_WAKEUP modification.
