net: Initialize all members in skb_gro_remcsum_init()
skb_gro_remcsum_init() initializes the gro_remcsum.delta member only, leading to compiler warnings about a possibly uninitialized gro_remcsum.offset member: drivers/net/vxlan.c: In function ‘vxlan_gro_receive’: drivers/net/vxlan.c:602: warning: ‘grc.offset’ may be used uninitialized in this function net/ipv4/fou.c: In function ‘gue_gro_receive’: net/ipv4/fou.c:262: warning: ‘grc.offset’ may be used uninitialized in this function While these are harmless for now: - skb_gro_remcsum_process() sets offset before changing delta, - skb_gro_remcsum_cleanup() checks if delta is non-zero before accessing offset, it's safer to let the initialization function initialize all members.
