media: verisilicon: AV1: Fix tile info buffer size

Browse Source 
Each tile info is composed of: row_sb, col_sb, start_pos
and end_pos (4 bytes each). So the total required memory
is AV1_MAX_TILES * 16 bytes.
Use the correct #define to allocate the buffer and avoid
writing tile info in non-allocated memory.
