[PATCH 5.4 47/51] xfs: fix uninitialized variable in xfs_attr3_leaf_inactive

[Greg Kroah-Hartman]

From: "Darrick J. Wong" <darrick.wong@xxxxxxxxxx>

commit 54027a49938bbee1af62fad191139b14d4ee5cd2 upstream.

Dan Carpenter pointed out that error is uninitialized.  While there
never should be an attr leaf block with zero entries, let's not leave
that logic bomb there.
