imd: don't recover on limit == 0

If the limit of the large starting region was set with
    a NULL pointer then the limit field will be 0. If the
    limit is zero then no attempt to recover is necessary
    as there is no region to recover.

This prevented an early call cbmem_find() from hanging a
    rambi device. The config was with vboot enabled and was
    way before memory init in the sequence.
