Subject: [PATCH 5.11 127/342] 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.
