Goldwyn Rodrigues e886355e3d btrfs: tracepoints: get correct superblock from dentry in event btrfs_sync_file() ...

[ Upstream commit a85b46db143fda5869e7d8df8f258ccef5fa1719 ]

If overlay is used on top of btrfs, dentry->d_sb translates to overlay's
super block and fsid assignment will lead to a crash.

Use file_inode(file)->i_sb to always get btrfs_sb.
