[PATCH v2] usb: host: tegra: remove pointless NULL check in tegra_ehci_remove()

[Wei Yongjun]

From: Wei Yongjun <yongjun_wei at trendmicro.com.cn>

Test for tegra and hcd in tegra_ehci_remove() look like potential
NULL pointer dereference, but in fact those tests are not needed,
so remove these pointless tests entirely.
