parallels: fix default options parsing 

parallels block driver is completely broken since commit
    commit 75cdcd1553
    Author: Markus Armbruster <armbru@redhat.com>

    option: Fix checking of sizes for overflow and trailing crap
Right now even simple
    qemu-io -c "read 512 64k" 1.hds
ends up with
    Unexpected error in parse_option_size() at util/qemu-option.c:188:
    Parameter 'prealloc-size' expects a non-negative number below 2^64
    Aborted (core dumped)
The cure is simple - we should use 'M' as a suffix in default option value
instead of 'MiB'.
