Fix add_nested_replacing_spare test case

Browse Source 
Use 'zpool reopen' instead of 'zpool scrub' to kick in the spare device:
this is required to avoid spurious failures caused by a race condition
in events processing by the ZFS Event Daemon:

P1 (zpool scrub)                            P2 (zed)
