net: lan743x: Fix memleak issue when GSO enabled

Browse source

[ Upstream commit 2d52e2e38b ]

Always map the `skb` to the LS descriptor. Previously skb was
mapped to EXT descriptor when the number of fragments is zero with
GSO enabled. Mapping the skb to EXT descriptor prevents it from
being freed, leading to a memory leak
