Maarten Lankhorst 18b072e8d5 dma-buf/dma-resv: Respect num_fences when initializing the shared fence list. 
commit bf8975837dac156c33a4d15d46602700998cb6dd upstream.

We hardcode the maximum number of shared fences to 4, instead of
respecting num_fences. Use a minimum of 4, but more if num_fences
is higher.

This seems to have been an oversight when first implementing the
api.

Fixes: 04a5faa8cbe5 ("reservation: update api and add some helpers")
