[PATCH] media: media videobuf2: Stop direct calls to queue num_buffers field

[Benjamin Gaignard]

Use vb2_get_num_buffers() to avoid using queue num_buffers field directly.
This allows us to change how the number of buffers is computed in the
future.

Fixes: c838530d230b ("media: media videobuf2: Be more flexible on the number of queue stored buffers")
