Daniel Mack 0b25f92943 usb: ehci-mxc: check for pdata before dereferencing ...

commit f375fc520d upstream.

Commit 7e8d5cd93f ("USB: Add EHCI support for MX27 and MX31 based
boards") introduced code that could potentially lead to a NULL pointer
dereference on driver removal.

Fix this by checking for the value of pdata before dereferencing it.
