[Intel-gfx] [PATCH linux-next] drm/i915: Remove redundant assignments

[luo penghao]

From: penghao luo <luo.penghao at zte.com.cn>

The assignment of variables will be overwritten later, so the
assignment here is meaningless.

The clang_analyzer complains as follows:

drivers/gpu/drm/i915/gem/i915_gem_userptr.c:291: warning:

Although the value stored to 'ret' is used in the enclosing expression,
the value is never actually read from 'ret’.
