gfs2: Fix iomap buffer head reference counting bug
GFS2 passes the inode buffer head (dibh) from gfs2_iomap_begin to
gfs2_iomap_end in iomap->private. It sets that private pointer in
gfs2_iomap_get. Users of gfs2_iomap_get other than gfs2_iomap_begin
would have to release iomap->private, but this isn't done correctly,
leading to a leak of buffer head references.
To fix this, move the code for setting iomap->private from
gfs2_iomap_get to gfs2_iomap_begin.
Fixes: 64bc06bb32 ("gfs2: iomap buffered write support")
