GFS2: Remove redundant metadata block type check
 
Function gfs2_inode_refresh calls gfs2_meta_inode_buffer, which itself
calls gfs2_meta_indirect_buffer with height 0. Since this path through
gfs2_meta_indirect_buffer makes a call to gfs2_metatype_check, the
call in gfs2_inode_refresh is redundant and just a waste of time.
This patch removes it.
