xfrm: Allow UDP encapsulation only in offload modes
[ Upstream commit 773bb766ca4a05bf363203030b72b10088869224 ]
The missing check of x->encap caused to the situation where GSO packets
were created with UDP encapsulation.
As a solution return the encap check for non-offloaded SA.
Fixes: 983a73da1f99 ("xfrm: Pass UDP encapsulation in TX packet offload")
Closes: https://lore.kernel.org/all/a650221ae500f0c7cf496c61c96c1b103dcb6f67.camel@redhat.com
