4.18-stable review patch. If anyone has any objections, please let me know.

From: Mathias Nyman mathias.nyman@linux.intel.com
commit f3dc41c5d22b2ca14a0802a65d8cdc33a3882d4e upstream.
usb_hc_died() should only be called once, and with the primary HCD as parameter. It will mark both primary and secondary hcd's dead.
Remove the extra call to usb_cd_died with the shared hcd as parameter.
