[GFS2] filesystem consistency error from do_strip
This patch fixes a GFS2 filesystem consistency error reported from function do_strip. The problem was caused by a timing window that allowed two vfs inodes to be created in memory that point to the same file. The problem is fixed by making the vfs's iget_test, iget_set mechanism check and set a new bit in the in-core gfs2_inode structure while the vfs inode spin_lock is held.
