[PATCH] pstore: make 'pstore_choose_compression' static

[Ben Dooks (Codethink)]

The pstore_choose_compression function is not exported
so make it static to avoid the following sparse warning:

fs/pstore/platform.c:796:13: warning: symbol 'pstore_choose_compression' was not declared. Should it be static?
