Haishuang Yan 5394976b6f ip_gre: fix parsing gre header in ipgre_err 
[ Upstream commit b0350d51f001e6edc13ee4f253b98b50b05dd401 ]

gre_parse_header stops parsing when csum_err is encountered, which means
tpi->key is undefined and ip_tunnel_lookup will return NULL improperly.

This patch introduce a NULL pointer as csum_err parameter. Even when
csum_err is encountered, it won't return error and continue parsing gre
header as expected.

Fixes: 9f57c67c379d ("gre: Remove support for sharing GRE protocol hook.")
