drivers: usb_dc_nrfx: clear endpoint flags during ep_disable()

If a loaded endpoint was disabled and then reconfigured,
it is not possible to start an IN transfer and
usb_dc_ep_write() returns -EAGAIN.

Call ep_ctx_reset() to clear endpoint operations flags
and reset buffer after endpoint is disabled.
