stmmac: intel: Fix clock handling on error and remove paths
clk_prepare_enable() might fail, we have to check its returned value.
Besides that we have to call clk_disable_unprepare() on the error and
remove paths. Do above in the dwmac-intel driver.
While at it, remove leftover in stmmac_pci and remove unneeded condition
for NULL-aware clk_unregister_fixed_rate() call.
