Colin Ian King 1bbbab097a drm/exynos: fix missing decrement of retry counter 
Currently the retry counter is not being decremented, leading to a
potential infinite spin if the scalar_reads don't change state.

Addresses-Coverity: ("Infinite loop")
Fixes: 280e54c9f6 ("drm/exynos: scaler: Reset hardware before starting the operation")
