usb: xhci: remove excessive Bulk short packet debug message

Completion codes 'COMP_SUCCESS' and 'COMP_SHORT_PACKET' are the most
frequently encountered completion codes. Typically, these codes do not
trigger a default debug message but rather a warning that indicates a
potential issue. This behavior is consistent across all transfer types
with the exception of Bulk transfers. To reduce unnecessary log clutter,
remove the Bulk 'COMP_SHORT_PACKET' debug message.
