Maxime Coquelin 9837e26077 vduse: Use proper spinlock for IRQ injection 
[ Upstream commit 7ca26efb09 ]

The IRQ injection work used spin_lock_irq() to protect the
scheduling of the softirq, but spin_lock_bh() should be
used.

With spin_lock_irq(), we noticed delay of more than 6
seconds between the time a NAPI polling work is scheduled
and the time it is executed.
