btrfs-progs: avoid double-free in __btrfs_map_block

__btrfs_map_block() can possibly do the goto again: loop after
having allocated & freed the "multi" pointer.  There are then
a couple error conditions where it will attempt to again kfree
the now non-NULL multi pointer.  So before retrying, reset
multi to NULL after we free it.
