exfat: add balloc parameter to exfat_map_cluster() for iomap support
In preparation for supporting the iomap infrastructure, we need to know
whether a new cluster was allocated or not in exfat_map_cluster().
Add an optional 'bool *balloc' output parameter. When a new cluster is
allocated, *balloc is set to true. Pass NULL from exfat_get_block() to
preserve the existing behavior.
