Subject: [PATCH AUTOSEL 4.9 12/12] btrfs: convert logic BUG_ON()'s in replace_path to ASSERT()'s

From: Josef Bacik <josef@...icpanda.com>

[ Upstream commit 7a9213a93546e7eaef90e6e153af6b8fc7553f10 ]

A few BUG_ON()'s in replace_path are purely to keep us from making
logical mistakes, so replace them with ASSERT()'s.
