btrfs: don't read from userspace twice in btrfs_uring_encoded_read()
If we return -EAGAIN the first time because we need to block,
btrfs_uring_encoded_read() will get called twice. Take a copy of args,
the iovs, and the iter the first time, as by the time we are called the
second time these may have gone out of scope.
