fsx was calling vfprintf twice without resetting the va_list argument

Merge of master-melb:xfs-cmds:28212a by kenmcd.

  fsx was calling vfprintf twice without resetting the va_list argument and
  this caused a segfault on the second call.  Now uses one call to vsnprintf
  to print to a buffer and uses that multiple times.
