Bluetooth: btmtk: Fix wait_on_bit_timeout interruption during shutdown 



During the shutdown process, an interrupt occurs that
prematurely terminates the wait for the expected event.
This change replaces TASK_INTERRUPTIBLE with
TASK_UNINTERRUPTIBLE in the wait_on_bit_timeout call to ensure
the shutdown process completes as intended without being
interrupted by signals.
