[PATCH 06/14] usb: dwc3-octeon-glue: check dev_remap_addr() for NULL

[David Lechner]

Check the return value of dev_remap_addr() for NULL instead of
IS_ERR(). This function only ever returns NULL on failure.

Drop the now-unused <linux/err.h> include.

Fixes: 92ca2fee08d5 ("usb: xhci: octeon: Add DWC3 glue layer for Octeon")
