btrfs: use vfs_utimes to update file timestamps

Browse source

Btrfs updates the device node timestamps for block device special files
when it stop using the device.

Commit 8f96a5bfa1 ("btrfs: update the bdev time directly when closing")
switch that update from the correct layering to directly call the
low-level helper on the bdev inode.  This is wrong and got fixed in
commit 54fde91f52 ("btrfs: update device path inode time instead of
bd_inode") by updating the file system inode instead of the bdev inode,
but this kept the incorrect bypassing of the VFS interfaces and file
system ->update_times method.  Fix this by using the propet vfs_utimes
interface.
