The function that handles xHCI command completion is much too long and
there is need to be broken up into individual functions for each command
completion to improve code readablity.
This patch refactors the code in TRB_ADDR_DEV switch case in
handle_cmd_completion() into a fuction named xhci_handle_cmd_addr_dev().
