[PATCH] ksmbd: use clear_and_wake_up_bit() in wake_up_oplock_break()

[Daijiamu <3058704216@qq.com>]

clear_and_wake_up_bit() was introduced by commit 8236b0ae31c8 ("bdi:
wake up concurrent wb_shutdown() callers.") to replace the open-coded
clear_bit_unlock() + smp_mb__after_atomic() + wake_up_bit() sequence.

Use the helper in wake_up_oplock_break() to standardize the code path.
