ixgbe: fix memory leaks in the ixgbe_recovery_probe() path
When ixgbe_recovery_probe() is invoked and this function fails,
allocated resources in advance are not completely freed, because
ixgbe_probe() returns ixgbe_recovery_probe() directly and
ixgbe_recovery_probe() only frees partial resources, resulting in memory
leaks including:
- adapter->io_addr
- adapter->jump_tables[0]
- adapter->mac_table
- adapter->rss_key
- adapter->af_xdp_zc_qps
The leaked MMIO region can be observed in /proc/vmallocinfo, and the
remaining leaks are reported by kmemleak.
Don't return ixgbe_recovery_probe() directly, and instead let
ixgbe_probe() to clean up resources on failures.
