[PATCH] usb: phy: tegra: Fix unnecessary check in tegra_usb_phy_probe()

[Tang Bin]

In the function tegra_usb_phy_probe(), if usb_add_phy_dev() failed,
the return value will be given to err, and if usb_add_phy_dev() succeed,
the return value will be zero. Thus it is unnecessary to repeated check
here.
