media: cx23885: Handle additional bufs on interrupt
On Ryzen systems interrupts are occasionally missed:
cx23885: cx23885_wakeup: [ffff99b384b83c00/28] wakeup reg=5406 buf=5405
cx23885: cx23885_wakeup: [ffff99b40bf79400/31] wakeup reg=9537 buf=9536
This patch loops up to five times on wakeup, marking any buffers
found done.
Since the count register is u16, but the vb2 counter is u32, some modulo
arithmetic is used to accommodate wraparound and ensure current active
buffer is the buffer expected.
