When delivering a hw-breakpoint SIGTRAP to a compat task via ptrace, the lack of a 'return' statement means we fallthrough to the native case, which differs in its handling of 'si_errno'. Although this looks to be harmless because the subsequent signal is effectively ignored, it's confusing and unintentional, so add the missing 'return'.

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.
