Herbert Xu 8053fc3de7 [IPSEC]: Temporarily remove locks around copying of non-atomic fields 
The change 050f009e16

	[IPSEC]: Lock state when copying non-atomic fields to user-space

caused a regression.

Ingo Molnar reports that it causes a potential dead-lock found by the
lock validator as it tries to take x->lock within xfrm_state_lock while
numerous other sites take the locks in opposite order.

For 2.6.24, the best fix is to simply remove the added locks as that puts
us back in the same state as we've been in for years.  For later kernels
a proper fix would be to reverse the locking order for every xfrm state
user such that if x->lock is taken together with xfrm_state_lock then
it is to be taken within it.
