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

Browse Source 
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 b17a57f89f ("xhci: Refactor
interrupter code for initial multi interrupter support."), but a
declaration in xhci.h still remains.  Drop it.
