drm/linux_ww_mutex: Fix wait loops.
If cv_wait_sig returns because a signal is delivered, we may
nonetheless have been granted the lock. It is harmless for us to
ignore this fact in three of the four paths, but in
ww_mutex_state_wait_sig, we may now have ownership of the lock and
MUST NOT return failure because the caller MUST release the lock
before destroying the ww_acquire_ctx.
While here, restructure the other three loops for clarity, so they
match the structure of the fourth and so they have a little less
impenetrable negation.
