gfs: Get rid of unnucessary locking in inode_go_dump
Commit 27a2660f1ef9 ("gfs2: Dump nrpages for inodes and their glocks")
added some locking around reading inode->i_data.nrpages. That locking
doesn't do anything really, so get rid of it.
With that, the glock argument to ->go_dump() can be made const again as
well.
