USB: xhci: Allow allocation of commands without input contexts.
The xhci_command structure is the basic structure for issuing commands to
the xHCI hardware. It contains a struct completion (so that the issuing
function can wait on the command), command status, and a input context
that is used to pass information to the hardware. Not all commands need
the input context, so make it optional to allocate. Allow
xhci_free_container_ctx() to be passed a NULL input context, to make
freeing the xhci_command structure simple.
