USB: xhci: Fix command wait list handling.
In the xHCI driver, configure endpoint commands that are submitted to the
hardware may involve one of two data structures. If the configure
endpoint command is setting up a new configuration or modifying max packet
sizes, the data structures and completions are statically allocated in the
xhci_virt_device structure. If the command is being used to set up
streams or add hub information, then the data structures are dynamically
allocated, and placed on a device command waiting list.
Break out the code to check whether a completed command is in the device
command waiting list. Fix a subtle bug in the old code: continue
processing the command if the command isn't in the wait list. In the old
code, if there was a command in the wait list, but it didn't match the
completed command, the completed command event would be dropped.
