stmmac: dwmac-intel-plat: fix call balance of tx_clk handling routines
If the clock dwmac->tx_clk was not enabled in intel_eth_plat_probe,
it should not be disabled in any path.
Conversely, if it was enabled in intel_eth_plat_probe, it must be disabled
in all error paths to ensure proper cleanup.
Found by Linux Verification Center (linuxtesting.org) with Klever.
