fs/ext4: fix log2blksz un-initialized error, by cacaulating its value from blksz
The problem here is that uboot can't mount ext4 filesystem with commit "50ce4c07df1" applied. We use hard-coded "SECTOR_SIZE"(512) before this commit, now we introduce (block_dev_desc_t *)->log2blksz to replace this macro. And after we calling do_ls()->fs_set_blk_dev(), the variable log2blksz is not initialized, which it's not correct. And this patch try to solve the problem by caculating the value of log2blksz from variable blksz.
