xhci: Don't free endpoints in xhci_mem_cleanup()
This patch fixes a few issues introduced in the recent fix
[f8a9e72d: USB: fix resource leak in xhci power loss path]
- The endpoints listed in bw table are just links and each entry is an
array member of dev->eps[]. But the commit above adds a kfree() call
to these instances, and thus it results in memory corruption.
- It clears only the first entry of rh_bw[], but there can be multiple
ports.
- It'd be safer to clear the list_head of ep as well, not only
removing from the list, as it's checked in
xhci_discover_or_reset_device().
This patch should be backported to kernels as old as 3.2, that contain
the commit 839c817ce67178ca3c7c7ad534c571bba1e69ebe "xhci: Store
information about roothubs and TTs."
