[FOR INTERNAL REVIEW] [PATCH RESEND 1/3] staging: erofs: fix incorrect code in erofs_shrink_scan

[Gao Xiang]

From: Gao Xiang <hsiangkao at aol.com>

This patch actually fixes incorrect code snippets due to spilt code
into small patches by mistake, which can cause a compile error without
built-in decompression support and potential abnormal runtime shrinking.
