io_uring: fix potential page leak in io_sqe_buffer_register()
If allocation of the 'imu' fails, then the existing pages aren't
unpinned in the error path. This is mostly a theoretical issue,
requiring fault injection to hit.
Move unpin_user_pages() to unified error handling to fix the page leak
issue.
