Subject: mtd: ubi: don't leak e if schedule_erase() fails

From: Sebastian Siewior <bigeasy@linutronix.de>

commit 6b238de189f69dc77d660d4cce62eed15547f4c3 upstream.

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.
