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

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.
