Subject: [PATCH] fs/xfs: Fix return code of xfs_break_leased_layouts()

From: Ira Weiny <ira.weiny@...el.com>

The parens used in the while loop would result in error being assigned
the value 1 rather than the intended errno value.

This is required to return -ETXTBSY from follow on break_layout()
changes.
