[PATCH v2 2/3] Btrfs: raid56: simplify the parameter of nr_parity_stripes().

We just need the type of a chunk to calculate the number of parity stripes, but we have to pass a structure of lookup_map to it. This will prevent some callers to use it where there is no a convenient lookup_map to be passed. This patch replace the parameter of struct map_lookup * with a profile
