usb: host: oxu210hp-hcd: Move declaration of 'qtd' into 'ifdef OXU_URB_TRACE'

Browse source

If we assign 'epnum' during the declaration we can also avoid "ISO
C90 forbids mixed declarations" issues.  So it does looks like we
can have our cake and eat it in this scenario.

Fixes the following W=1 kernel build warning(s):

 drivers/usb/host/oxu210hp-hcd.c: In function ‘submit_async’:
 drivers/usb/host/oxu210hp-hcd.c:2040:19: warning: variable ‘qtd’ set but not used [-Wunused-but-set-variable]
 2040 | struct ehci_qtd *qtd;
 | ^~~
