[PATCH] cramfs: fix usage on non-MTD device

[Nicolas Pitre <nico@xxxxxxxxxxx>]

From: Maxime Bizon <mbizon@xxxxxxxxxx>

When both CONFIG_CRAMFS_MTD and CONFIG_CRAMFS_BLOCKDEV are enabled, if
we fail to mount on MTD, we don't try on block device.

Fixes: 74f78fc5ef43 ("vfs: Convert cramfs to use the new mount API")
