usb: xhci: remove duplicate code from 'xhci_clear_command_ring()'

Browse Source 
Replace a segment of code within 'xhci_clear_command_ring()' with a
function call to 'xhci_initialize_ring_info()'. This change eliminates
code duplication, as 'xhci_initialize_ring_info()' performs the same
operations as the replaced code.
