Kuniyuki Iwashima a594920f87 inet: Remove an unnecessary argument of syn_ack_recalc(). 
Commit 0c3d79bce4 ("tcp: reduce SYN-ACK
retrans for TCP_DEFER_ACCEPT") introduces syn_ack_recalc() which decides
if a minisock is held and a SYN+ACK is retransmitted or not.

If rskq_defer_accept is not zero in syn_ack_recalc(), max_retries always
has the same value because max_retries is overwritten by rskq_defer_accept
in reqsk_timer_handler().

This commit adds three changes:
- remove redundant non-zero check for rskq_defer_accept in
   reqsk_timer_handler().
- remove max_retries from the arguments of syn_ack_recalc() and use
   rskq_defer_accept instead.
- rename thresh to max_syn_ack_retries for readability.

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.
