Veaceslav Falico 5b9e9be775 af_packet: block BH in prb_shutdown_retire_blk_timer() ...

[ Upstream commit ec6f809ff6 ]

Currently we're using plain spin_lock() in prb_shutdown_retire_blk_timer(),
however the timer might fire right in the middle and thus try to re-aquire
the same spinlock, leaving us in a endless loop.

To fix that, use the spin_lock_bh() to block it.

Fixes: f6fb8f100b ("af-packet: TPACKET_V3 flexible buffer implementation.")
