usb: xhci: improve xhci_clear_command_ring()
Remove redundant TRB cycle reset, the TRB cycle is already set to zero by
the preceding memset(), making the explicit reset unnecessary.
Clarify ring loop start point. Change the loop start from the dequeue
segment to the start segment. Both approaches achieve the same result,
but starting from the start segment makes it clearer that the entire ring
is being zeroed out.
