Every caller of function gfs2_struct2blk specified sizeof(u64). This patch eliminates the unnecessary parameter and replaces the size calculation with a new superblock variable that is computed to be the maximum number of block pointers we can fit inside a log descriptor, as is done for pointers per dinode and indirect block.
