Christian Brauner a779e27f24 coredump: fix core_pattern input validation
In be1e028302 ("coredump: don't pointlessly check and spew warnings")
we tried to fix input validation so it only happens during a write to
core_pattern. This would avoid needlessly logging a lot of warnings
during a read operation. However the logic accidently got inverted in
this commit. Fix it so the input validation only happens on write and is
skipped on read.

Fixes: be1e028302 ("coredump: don't pointlessly check and spew warnings")
Fixes: 16195d2c7d ("coredump: validate socket name as it is written")

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 reStructuredText 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.
