staging: r8188eu: summarize common Queue2Pipe settings

Regardless of the number of endpoints, queues 4 to 7 are mapped to pipe 0.
Move these mappings to rtl8188eu_interface_configure to make the code
simpler.

It's ok to make these settings even if we exit with error later. In this
case, the driver will not be loaded and pdvobjpriv->Queue2Pipe[] will be
freed.
