Subject: [PATCH] gve: Fix an error handling path in 'gve_probe()'
Git-commit: 2342ae10d1272d411a468a85a67647dd115b344f
Patch-mainline: v5.14-rc2
References: git-fixes

If the 'register_netdev() call fails, we must release the resources
allocated by the previous 'gve_init_priv()' call, as already done in the
remove function.

Add a new label and the missing 'gve_teardown_priv_resources()' in the
error handling path.

Fixes: 893ce44df565 ("gve: Add basic driver framework for Compute Engine Virtual NIC")
