xhci: Clean up xhci_{alloc,free}_erst() declarations

xhci_alloc_erst() has global scope even though it's only used in xhci-mem.c. Declare it static. xhci_free_erst() was removed by commit b17a57f ("xhci: Refactor interrupter code for initial multi interrupter support."), but a declaration in xhci.h still remains. Drop it.
