GFS2: Fix a use-after-free that coverity spotted
In function gfs2_inplace_release it was trying to unlock a gfs2_holder structure associated with a reservation, after said reservation was freed. The problem is that the statements have the wrong order. This patch corrects the order so that the reservation is freed after the gfs2_holder is unlocked.
