initramfs: avoid static buffer for error message
The dynamic error message printed if CONFIG_RD_$ALG compression support
is missing needn't be propagated up to the caller via a static buffer.
Print it immediately via pr_err() and set @message to a const string to
flag error.

Before:
   text    data     bss     dec     hex filename
   8006    1118       8    9132    23ac init/initramfs.o

After:
   text    data     bss     dec     hex filename
   7938    1022       8    8968    2308 init/initramfs.o

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.
