[PATCH v2 59/62] mtd: ubi: don't leak e if schedule_erase() fails

[Teresa Remmet]

From: Sebastian Siewior <bigeasy at linutronix.de>

If __erase_worker() fails to erase the EB and schedule_erase() fails as
well to do anything about it then we go RO. But that is not a reason to
leak the e argument here. Therefore clean up e.
