Revert "UPSTREAM: usb: dwc3: gadget: disable XFER_NOT_READY"

Browse Source 
This reverts commit 2a1f2d1e89.

Refer to DWC3 databook, Table 7-7 Device Endpoint-n Events(DEPEVT),
XferNotReady is generated when the core responds NRDY to the host
on the USB. It is useful in the beginning of a transfer when
software wants to wait for the host to start polling the endpoint
before setting up TRBs. And also refer to 8.2.4 Transfer Setup
Recommendations, when using on-demand transfers, the XferNotRead
event must be enabled.

TEST=Set usb gadget work as RNDIS, connect to win7/win10, check
the RNDIS function
