gfs2: Free rd_bits later in gfs2_clear_rgrpd to fix use-after-free
[ Upstream commit d0f17d3883f1e3f085d38572c2ea8edbd5150172 ]
Function gfs2_clear_rgrpd calls kfree(rgd->rd_bits) before calling
return_all_reservations, but return_all_reservations still dereferences
rgd->rd_bits in __rs_deltree. Fix that by moving the call to kfree below the
call to return_all_reservations.
