Ming Lei aaeee62c84 block: fix updating bio's front segment size 
When the current bvec can be merged to the 1st segment, the bio's front
segment size has to be updated.

However, dcebd75592 doesn't consider that case, then bio's front
segment size may not be correct.

This patch fixes this issue.

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.
