Subject: Btrfs: remove BUG() in btrfs_extent_inline_ref_size
Git-commit: 4335958de2a43c6790c7f6aa0682aa7189983fa4
Patch-mainline: v4.14-rc1
References: bsc#1149325

Now that btrfs_get_extent_inline_ref_type() can report if type is a
valid one and all callers can gracefully deal with that, we don't need
to crash here.
