net: stmmac: selftests: fix potential memleak in stmmac_test_arpoffload()

[ Upstream commit f150b63f3fa5fdd81e0dd6151e8850268e29438c ]

The skb allocated by stmmac_test_get_arp_skb() hasn't been released in
some error handling case, which will lead to a memory leak. Fix this up
by adding kfree_skb() to release skb.

Compile tested only.
