This patch fixes a coding style issue reported by checkpatch related to
too many leading tabs.

This moves part of the fill_periodic_buffer() to the new function
output_buf_tds_dir().

Because it's inline, the file size has not changed.

Before:
  text data  bss    dec   hex filename

After:
  text data  bss    dec   hex filename
 36920    81   12  37013  9095  drivers/usb/host/ehci-hcd.o
