[PATCH 10/10] staging: r8188eu: set pipe only once

[Martin Kaiser]

Set the pipe for reading or writing in usbctrl_vendorreq only once.
There's no need to set it again for every retry.

This patch is an adaptation of commit 889ed8b5e374 ("staging: rtl8188eu:
set pipe only once") for the new r8188eu driver.
