    Fix unused variable warning in rockchip's rk_spi.c
    
    With clang 15, the following -Werror warning is produced:
    
        sys/arm64/rockchip/rk_spi.c:229:6: error: variable 'cnt' set but not used [-Werror,-Wunused-but-set-variable]
                int cnt = 0;
                    ^
    
    The 'cnt' variable was in rk_spi.c when it was first added, but it
    appears to have been a debugging aid that has never been used, so remove
    it.
    
    MFC after:      3 days
    
    (cherry picked from commit 0fe8ab6851687dc7249e3c5b5df3d6723d1c3e7a)
