Subject: usb: phy: tegra: Fix unnecessary check in tegra_usb_phy_probe()

Git-commit: d410912ef63714fad404f34baa72e5ceb0466e62
Patch-mainline: v5.8-rc3
References: jsc#SLE-15847

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.
