litex_liteeth: Fix a double free in the remove function

BugLink: https://bugs.launchpad.net/bugs/1951822
[ Upstream commit c45231a7668d6b632534f692b10592ea375b55b0 ]

'netdev' is a managed resource allocated in the probe using
'devm_alloc_etherdev()'.
It must not be freed explicitly in the remove function.
