Ilia Gavrilov 239af1970b llc: fix data loss when reading from a socket in llc_ui_recvmsg()

For SOCK_STREAM sockets, if user buffer size (len) is less
than skb size (skb->len), the remaining data from skb
will be lost after calling kfree_skb().

To fix this, move the statement for partial reading
above skb deletion.
