[PATCH] orangefs: print debug on op before it is freed by set_op_state_purged

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

static analysis shows that calling gossip_debug on op is problematic
because op freed by the previous call to set_op_state_purged. Fix
this by printing the debug before freeing op.
