[0/2] USB static analysis patches

Message

These two patches are a result of running the Parfait static analysis
tool on QEMU.  The first patch is an optimisation to move an assignment
after a test and the second patch handles a number of potential NULL
pointer dereferences if usb_ep_get() returns NULL.

Liam Merwick (2):
  usb: rearrange usb_ep_get()
  usb: deal with potential Null pointer returned by usb_ep_get()
