USB: gadget : Fix RNDIS code to pass USB Compliance tests (USBCV) with g_ether
This patch fixes a bug in the RNDIS code.
Due to this bug gether_connect() fails as the port remains un-initialized.
As a result following USB Compliance Tests were failing.
(1)EndpointDescriptorTest_DeviceConfigured
(2)Interface Descriptor Test.
(3)Halt Endpoint Test.
(4)SetConfigurationTest
The fix aligns rndis code with the CDC ECM for xxx_set_alt().
The above listed USB Compliance test passes with this fix.
Tested working fine on SDP with OMAP 3430.
