net: ife: require ETH_HLEN to be pullable in ife_decode()

In the Linux kernel, the following vulnerability has been resolved:

net: ife: require ETH_HLEN to be pullable in ife_decode()

ife decode may return after making only the outer IFE header and
metadata pullable. The caller then passes the decapsulated packet to
eth_type_trans(), which expects the inner Ethernet header to be
accessible from the linear data area.

With a malformed IFE frame, the inner Ethernet header may still be
shorter than ETH_HLEN in the linear area, which can lead to a crash in
the original code.

Fix this by extending the pull check in ife_decode() so that the inner
Ethernet header is also guaranteed to be pullable before returning.
