[SRU][Jammy][Focal][PATCH 1/1] phy: tegra: xusb: Fix return value of tegra_xusb_find_port_node function

[Bethany Jamison]

From: Miaoqian Lin <linmq006 at gmail.com>

callers of tegra_xusb_find_port_node() function only do NULL checking for
the return value. return NULL instead of ERR_PTR(-ENOMEM) to keep
consistent.
