[PATCH 3/5] xfrm: Allow UDP encapsulation in crypto offload control path

[Steffen Klassert <steffen.klassert@secunet.com>]

From: Mike Yu <yumike@google.com>

Unblock this limitation so that SAs with encapsulation specified
can be passed to HW drivers. HW drivers can still reject the SA
in their implementation of xdo_dev_state_add if the encapsulation
is not supported.

Test: Verified on Android device
