[PATCH v1 3/3] f2fs/{019,020}: clear MOUNT_OPTIONS alongside MKFS_OPTIONS

[Joanne Chang <joannechien@google.com>]

Currently, f2fs/019 and f2fs/020 only clears MKFS_OPTIONS. This causes
the tests to fail when leftover MOUNT_OPTIONS depend on unapplied
MKFS_OPTIONS. So MOUNT_OPTIONS should also be cleared to ensure reliable
mounting.
