xfs: fix memory leak for data allocated by xfs_zone_gc_data_alloc()

In xfs_zone_gc_mount(), on error, a struct xfs_zone_gc_data allocated
with xfs_zone_gc_data_alloc() is freed with kfree(), however, this
doesn't free the underlying folios or the rmap_irecs.

Use xfs_zone_gc_data_free() to correctly free this memory.
