iscsi_ibft: Fix UBSAN shift-out-of-bounds warning in ibft_attr_show_nic()
[ Upstream commit 07e0d99a2f701123ad3104c0f1a1e66bce74d6e5 ]
When performing an iSCSI boot using IPv6, iscsistart still reads the
/sys/firmware/ibft/ethernetX/subnet-mask entry. Since the IPv6 prefix
length is 64, this causes the shift exponent to become negative,
triggering a UBSAN warning. As the concept of a subnet mask does not
apply to IPv6, the value is set to ~0 to suppress the warning message.
