    Fix unused variable warning in usb's atp.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/dev/usb/input/atp.c:2018:11: error: variable 'n_vertical_scrolls' set but not used [-Werror,-Wunused-but-set-variable]
                u_int8_t n_vertical_scrolls = 0;
                         ^
    
    The 'n_vertical_scrolls' variable is no longer used after 197b9a2ef003,
    so remove it.
    
    MFC after:      3 days
