btrfs: remove redundant else statement from btrfs_log_inode_parent()

If we don't need to log new directory dentries, there's no point in having
an else branch just to set 'ret' to zero, as it's already zero because
every time it gets a non-zero value we jump into one of the exit labels.

So remove it, which reduces source code size and the module text size.

Before this change:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  1813855	 163737	  16920	1994512	 1e6f10	fs/btrfs/btrfs.ko

After this change:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  1813807	 163737	  16920	1994464	 1e6ee0	fs/btrfs/btrfs.ko
