phy: tegra: xusb: remove a stray unlock

We used to take a lock in tegra186_utmi_bias_pad_power_on() but now we have moved the lock into the caller. Unfortunately, when we moved the lock this unlock was left behind and it results in a double unlock. Delete it now.

Fixes b47158fb4295 ("phy: tegra: xusb: Use a bitmask for UTMI pad power state tracking")

Thanks for catching and fixing this!
