Sandeep Dhavale e07fec475c usb: gadgetfs: Fix ep_read_iter to handle ITER_UBUF
iov_iter for ep_read_iter can be ITER_UBUF with io_uring.
In that case dup_iter() does not have to allocate iov and it can
return NULL. Fix the assumption by checking for iter_is_ubuf()
other wise ep_read_iter can treat this as failure and return -ENOMEM.

Fixes: 1e23db450c ("io_uring: use iter_ubuf for single range imports")
