forcedeth: Fix an error handling path in nv_probe()
commit 5b17a4971d3b2a073f4078dd65331efbe35baa2d upstream.
If an error occures after calling nv_mgmt_acquire_sema(), it should be
undone with a corresponding nv_mgmt_release_sema() call.
Add it in the error handling path of the probe as already done in the
remove function.
Fixes: cac1c52c3621 ("forcedeth: mgmt unit interface")
