s390/bpf: Fix offset parameter for skb_copy_bits()
Currently the offset parameter for skb_copy_bits is changed in sk_load_word() and sk_load_half(). Therefore it is not correct when calling skb_copy_bits(). Fix this and use the original offset for the function call. Signed-off-by: Michael Holzheu <holzheu@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
