udp: properly support MSG_PEEK with truncated buffers
Backport of this upstream commit into stable kernels :
89c22d8c3b27 ("net: Fix skb csum races when peeking")
exposed a bug in udp stack vs MSG_PEEK support, when user provides
a buffer smaller than skb payload.
...
NOTE: The test will hang on unpatched stable kernels.
