media: atomisp: make atomisp_css_continuous_set_num_raw_frames() void

The return value of atomisp_css_continuous_set_num_raw_frames() function is always 0, so there's no reason for a return value. In addition, the __enable_continuous_mode() checked the return value for possible error which is unnecessary. Convert atomisp_css_continuous_set_num_raw_frames() to a void function.
