gfs2: Use sb_start_intwrite in gfs2_ail_empty_gl
Commit 2e60d7683c8d ("GFS2: update freeze code to use freeze/thaw_super
on all nodes") optimized away the sb_start_intwrite ... sb_end_intwrite
protection for the on-stack transactions in gfs2_ail_empty_gl with no
explanation. I can't think of a valid reason for doing that, so revert
that change. This simplifies the next commit.
