[GFS2] Remove gfs2_inode_attr_in
This function wasn't really doing the right thing. There was no need to update the inode size at this point and the updating of the i_blocks field has now been moved to the places where di_blocks is updated. A result of this patch and some those preceeding it is that unlocking a glock is now a much more efficient process, since there is no longer any requirement to copy data from the gfs2 inode into the vfs inode at this point.
