Subject: [PATCH -next] drbd: Remove unused extern declarations

From: YueHaibing <yuehaibing@...wei.com>

Commit b411b3637fa7 ("The DRBD driver") declared but never implemented
drbd_read_remote(), is_valid_ar_handle() and drbd_set_recv_tcq().
And commit 668700b40a7c ("drbd: Create a dedicated workqueue for sending acks on the control connection")
never implemented drbd_send_ping_wf().

Commit 2451fc3b2bd3 ("drbd: Removed the BIO_RW_BARRIER support form the receiver/epoch code")
leave w_e_reissue() declaration unused.

Commit 8fe605513ab4 ("drbd: Rename drbdd_init() -> drbd_receiver()")
rename drbdd_init() and leave unsued declaration. Also drbd_asender() is removed in
commit 1c03e52083c8 ("drbd: Rename asender to ack_receiver").
