Mathias Nyman fe465003bb xhci: fix possible null pointer dereference at secondary interrupter removal 
commit a54a594d72 upstream.

Don't try to remove a secondary interrupter that is known to be invalid.
Also check if the interrupter is valid inside the spinlock that protects
the array of interrupters.
