btrfs: ioctl: don't free iov when btrfs_encoded_read() returns -EAGAIN
Fix a bug in encoded read that mistakenly frees the iov in case
btrfs_encoded_read() returns -EAGAIN assuming the structure will be
reused. This can happen when when receiving requests concurrently, the
io_uring subsystem does not reset the data, and the last free will
happen in btrfs_uring_read_finished().
Handle the -EAGAIN error and skip freeing iov.
