Bluetooth: hci_qca: Fix "Sleep inside atomic section" warning
This patch fixes the following warning during boot: do not call blocking ops when !TASK_RUNNING; state=1 set at [<(ptrval)>] qca_setup+0x194/0x750 [hci_uart] WARNING: CPU: 2 PID: 1878 at kernel/sched/core.c:6135 __might_sleep+0x7c/0x88 In qca_set_baudrate(), the current task state is set to TASK_UNINTERRUPTIBLE before going to sleep for 300ms. It was then restored to TASK_INTERRUPTIBLE. This patch sets the current task state back to TASK_RUNNING instead.
