fuse_lowlevel.c: fix possible 64 bits value truncation
Because conn.want_ext is a uint64_t, copying it into a uint32_t may result
in truncating it's value. This patch fixes a bug in do_init() where the
32 bits copy is again converted into a 64 bits value, because it will be
used in convert_to_conn_want_ext().
