msm: camera: sensor: Reg settings missed while lookahead on qup

While we lookahead and merge the continuous reg settings to
burst, the packed setting len with uint8 data type may happen
overflow if the continuous reg setting count is larger than 255,
then some reg settings missed and lead to some sensor issues,
so modify the data type of len to avoid it.
