xhci: fix list access before init
commit 88696ae432ce7321540ac53d9caab3de9118b094 upstream.
If for whatever reason we fall into fail path in xhci_mem_init()
before bw table gets initialized we may access the uninitialized lists
in xhci_mem_cleanup().
Check for bw table before traversing lists in cleanup routine.
This patch should be backported to kernels as old as 3.2, that contain
the commit 839c817ce67178ca3c7c7ad534c571bba1e69ebe "xhci: Store
information about roothubs and TTs."
