Luke Nowakowski-Krijger 9fa3e0882a media: hdpvr: Add device num check and handling 
[ Upstream commit d4a6a9537b ]

Add hdpvr device num check and error handling

We need to increment the device count atomically before we checkout a
device to make sure that we do not reach the max count, otherwise we get
out-of-bounds errors as reported by syzbot.
