[Intel-wired-lan] [PATCH iwl-net v1] ixgbe: fix memory leaks in ixgbe_recovery_probe()

[Kohei Enju]

ixgbe_recovery_probe() does not free the following resources in its
error path, unlike ixgbe_probe():
- 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.

Free these allocations and unmap the MMIO region on failure to avoid the
leaks.

Fixes: 29cb3b8d95c7 ("ixgbe: add E610 implementation of FW recovery mode")
