btrfs: always return -EIOCBQUEUED after btrfs_uring_read_extent_endio

Browse source

If all bios finish before btrfs_encoded_read_regular_fill_pages()
returns, it calls btrfs_uring_read_extent_endio() and previously
returned the I/O status.  A negative errno then made
btrfs_uring_read_extent() unlock and free while
btrfs_uring_read_finished() did the same again.

Return -EIOCBQUEUED so only the deferred path cleans up.
