[ Upstream commit 7777f47f2ea64efd1016262e7b59fab34adfb869 ] Commit1a721de848("block: don't add or resize partition on the disk with GENHD_FL_NO_PART") prevented all operations about partitions on disks with GENHD_FL_NO_PART in blkpg_do_ioctl() since they are meaningless. However, it changed error code in some scenarios. So move checking GENHD_FL_NO_PART to bdev_add_partition() to eliminate impact.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
