media: atomisp: Simplify v4l2_fh_open() error handling

v4l2_fh_open() can only fail with -ENOMEM and as a generic rule drivers
do not log their own errors for -ENOMEM since the kernel will already
have complained loudly about this before the -ENOMEM return.

Remove the unnecessary error logging from atomisp_open().
