In sbin/camcontrol/camcontrol.c, function smpcmd(), initialize the
'error' variable to zero, to avoid returning garbage in several cases.

This fixes the following clang 3.2 warnings:

  sbin/camcontrol/camcontrol.c:4634:8: warning: variable 'error' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized]
                          if (amt_written == -1) {
                              ^~~~~~~~~~~~~~~~~
  sbin/camcontrol/camcontrol.c:4656:10: note: uninitialized use occurs here
          return (error);
                  ^~~~~
