Bug #11881

Updated by Toomas Soome over 2 years ago

FreeBSD commit: https://svnweb.freebsd.org/changeset/base/353757 

 When zfs probe did fail and no spa was created, but zfs_fmtdev() is called, we will crash while dereferencing spa (NULL pointer dereference). 

 Tested with userland loader/zfs reader app where the issue did reveal itself (app is not yet in illumos tree) - did confirm the crash does not happen any more.
