svn commit: r271227 - head/cddl/contrib/opensolaris/cmd/zpool

[Xin LI]

Author: delphij

New Revision: 271227
URL: http://svnweb.freebsd.org/changeset/base/271227

Log:
  MFV r271225:
  
  Iterate through all the children instead of returning error when we hit
  the first error.  This makes the error message give more information
  rather than just the first device that causes problem.
  
  Illumos issue:
      5118 When verifying or creating a storage pool, error messages only
  	 show one device
  
  MFC after:	2 weeks
