Subject: [PATCH 4.19 08/84] f2fs: Move err variable to function scope in f2fs_fill_dentries()

From: Ben Hutchings <ben.hutchings@...ethink.co.uk>

This is preparation for the following backported fixes.  It was done
upstream as part of commit e1293bdfa01d "f2fs: plug readahead IO in
readdir()", the rest of which does not seem suitable for stable.
