Variable ret is assigned a value that is never read; it is either
being re-assigned during the following while-loop or after the loop.
The assignmnt is redundant and can be removed.

Cleans up clang scan build warning:
drivers/gpu/drm/i915/gem/i915_gem_userptr.c:295:11: warning: Although
the value stored to 'ret' is used in the enclosing expression, the
value is never actually read from 'ret' [deadcode.DeadStores]
