[ Upstream commit ac322f86b56cb99d1c4224c209095aa67647c967 ]
While unloading the dwmac-intel driver, clk_disable_unprepare() is
being called twice in stmmac_dvr_remove() and
intel_eth_pci_remove(). This causes kernel panic on the second call.
Removing the second call of clk_disable_unprepare() in
intel_eth_pci_remove().
Fixes: 09f012e64e4b ("stmmac: intel: Fix clock handling on error and remove paths")
