Zhihao Cheng 1e020e1b96 ubi: Fix failure attaching when vid_hdr offset equals to (sub)page size 
Following process will make ubi attaching failed since commit
1b42b1a36f ("ubi: ensure that VID header offset ... size"):

ID="0xec,0xa1,0x00,0x15" # 128M 128KB 2KB
modprobe nandsim id_bytes=$ID
flash_eraseall /dev/mtd0
modprobe ubi mtd="0,2048"  # set vid_hdr offset as 2048 (one page)
(dmesg):
  ubi0 error: ubi_attach_mtd_dev [ubi]: VID header offset 2048 too large.
  UBI error: cannot attach mtd0
  UBI error: cannot initialize UBI, error -22

Rework original solution, the key point is making sure
'vid_hdr_shift + UBI_VID_HDR_SIZE < ubi->vid_hdr_alsize',
so we should check vid_hdr_shift rather not vid_hdr_offset.
Then, ubi still support (sub)page aligined VID header offset.

Fixes: 1b42b1a36f ("ubi: ensure that VID header offset ... size")

README 

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.
