Li Lingfeng 072cd213c6 block: don't add or resize partition on the disk with GENHD_FL_NO_PART
[ Upstream commit 1a721de8489fa559ff4471f73c58bb74ac5580d3 ]

Commit a33df75c6328 ("block: use an xarray for disk->part_tbl") remove
disk_expand_part_tbl() in add_partition(), which means all kinds of
devices will support extended dynamic `dev_t`.
However, some devices with GENHD_FL_NO_PART are not expected to add or
resize partition.
Fix this by adding check of GENHD_FL_NO_PART before add or resize
partition.
