The variable ret is being assigned with a value that is never read

i915_gem_object_lock_interruptible. Remove the redundants assignments.
Cleans up clang scan-build warnings:
warning: Although the value stored to 'ret' is used in the
enclosing expression, the value is never actually read
from 'ret' [deadcode.DeadStores]
