gfs2: take jdata unstuff into account in do_grow



[ Upstream commit bc0205612bbd4dd4026d4ba6287f5643c37366ec ]

Before this patch, function do_grow would not reserve enough journal
blocks in the transaction to unstuff jdata files while growing them.
This patch adds the logic to add one more block if the file to grow
is jdata.
