gfs2: clear buf_in_tr when ending a transaction in sweep_bh_for_rgrps
In function sweep_bh_for_rgrps, which is a helper for punch_hole,
it uses variable buf_in_tr to keep track of when it needs to commit
pending block frees on a partial delete that overflows the
transaction created for the delete. The problem is that the
variable was initialized at the start of function sweep_bh_for_rgrps
but it was never cleared, even when starting a new transaction.
This patch reinitializes the variable when the transaction is
ended, so the next transaction starts out with it cleared.
Fixes: d552a2b9b33e ("GFS2: Non-recursive delete")
