[PATCH] ov9655: fix potential integer overflow

["Gustavo A. R. Silva" <gustavo@embeddedor.com>]

Add suffix ULL to constant 10000 rather than casting the result of the
operation in order to avoid a potential integer overflow. This constant
is used in a context that expects an expression of type u64.
