pstore: fix compression

From: Jiri Bohac
Date: Thu Feb 18 2021 - 08:02:11 EST


pstore_compress() and decompress_record() use a mistyped config option
name ("PSTORE_COMPRESSION" instead of "PSTORE_COMPRESS").
As a result compression and decompressionm of pstore records is always
disabled.

Use the correct config option name.
