[PATCH v2 023/148] net/ice/base: fix memory leak when checking firmware version

[Anatoly Burakov]

From: Ian Stokes <ian.stokes at intel.com>

If ice_cfg_phy_fec() goes through case ICE_FEC_DIS_AUTO but the underlying
device firmware isn't the correct version, then the memory used to hold the PHY
capabilities output from the firmware isn't freed.

Fix this by making sure the memory is freed by jumping to the label that frees
the memory instead of returning from the version check immediately.
