btrfs: convert kmalloc_array to kmalloc_objs in btrfs_calc_avail_data_space()

There's one use of kmalloc_array() that can be transformed to
kmalloc_objs() in the same way as suggested in commit 69050f8d6d075d
("treewide: Replace kmalloc with kmalloc_obj for non-scalar types"),
swap the arguments and drop GFP flags. All the other cases of
kmalloc_array() do not use a simple type so this is the only one.
