Subject: UBI: fix EBADMSG handling

'ubi_io_read_data()' may return EBADMSG in case of an ECC error,
and we should not panic because of this. We have CRC32 checksum
and may check the data. So just ignore the EBADMSG error.

This patch also fixes a minor spelling error at the same time.

Subject: UBI: Don't exit from ubi_thread until kthread_should_stop() is true

If ubi_thread() exits but kthread_should_stop() is not true
then kthread_stop() will never return and cleanup thread
will forever stay in "D" state.
