ublk: refactor common helper ublk_shmem_remove_ranges()
Extract the shared walk+erase+unpin+kfree loop into
ublk_shmem_remove_ranges(). When buf_index >= 0, only ranges matching
that index are removed; when buf_index < 0, all ranges are removed.
Also extract ublk_unpin_range_pages() to share the page unpinning
loop.
Convert both __ublk_ctrl_unreg_buf() and ublk_buf_cleanup() to use
the new helper.
