ext4: "ret" may be used uninitialized in ext4_lazyinit_thread() 

Newer GCC's reported the following build warning:

   fs/ext4/super.c: In function 'ext4_lazyinit_thread':
   fs/ext4/super.c:2702: warning: 'ret' may be used uninitialized in this function

Fix it by removing the need for the ret variable in the first place.
