xhci: refactor TRB_DISABLE_SLOT case into function
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_DISABLE_SLOT switch case in handle_cmd_completion() into a fuction named xhci_handle_cmd_disable_slot().
