mlxsw: switchx2: Fix memory leak at skb reallocation
[ Upstream commit 400fc0106dd8c27ed84781c929c1a184785b9c79 ]
During transmission the skb is checked for headroom in order to
add vendor specific header. In case the skb needs to be re-allocated,
skb_realloc_headroom() is called to make a private copy of the original,
but doesn't release it. Current code assumes that the original skb is
released during reallocation and only releases it at the error path
which causes a memory leak.
Fix this by adding the original skb release to the main path.
