[PATCH] ext3: use sbi instead of EXT3_SB() in resize code.

[glommer@br.ibm.com (Glauber de Oliveira Costa)]

[-- Attachment #1: Type: text/plain, Size: 352 bytes --]

There are places in the resize code in which EXT3_SB() macro is used
after an statement like sbi = EXT3_SB(sb) is done. Inside the same 
function, both sbi and EXT3_SB() are used to reference the super block
Altough it is not wrong, keeping it coherent increases legibility, IMHO.
