[PATCH -next] drm/tegra: sor: Fix invalid kfree of devm_kzalloc allocated data

[weiyj_lk at 163.com]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

data allocated with devm_kzalloc should not be freed using kfree,
because doing so causes a dangling pointer, and a subsequent
double free, use devm_kfree instead.
