dma_buf: change unsigned int and int types into size_t

Browse Source 
The num_fences, count, i, and j variables in dma_fence_dedup_array() and
__dma_fence_unwrap_merge() have inconsistent integer types, mixing both
unsigned int and int.

Use type size_t consistently for these instead, and update the return
type of dma_fence_dedup_array() accordingly.
