Filipe Manana a5b3f117da btrfs: move btrfs_is_empty_uuid() from ioctl.c into fs.c ...

It's a generic helper not specific to ioctls and used in several places,
so move it out from ioctl.c and into fs.c. While at it change its return
type from int to bool and declare the loop variable in the loop itself.

This also slightly reduces the module's size.

Before this change:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  1781492	 161037	  16920	1959449	 1de619	fs/btrfs/btrfs.ko

After this change:

  $ size fs/btrfs/btrfs.ko
     text	   data	    bss	    dec	    hex	filename
  1781340	 161037	  16920	1959297	 1de581	fs/btrfs/btrfs.ko
