[media] tw5864-core: remove excessive irqsave
As warned by smatch:
drivers/media/pci/tw5864/tw5864-core.c:160 tw5864_h264_isr() error: double lock 'irqsave:flags'
drivers/media/pci/tw5864/tw5864-core.c:174 tw5864_h264_isr() error: double unlock 'irqsave:flags'
Two different spinlocks are obtained, so having two calls is correct,
but second irqsave is superfluous, and using same "flags" variable is
just wrong.
