Xen devel - Sep 2006 - [PATCH][vTPM][XM-TEST] echo command string break-up fix

When redirecting the output of the echo command using ''>''
on bash, the
output seems to be broken up into multiple write()s (depending on the
version of busybox?). Unfortunately /dev/tpm0 needs to have the complete
command written to in one chunk. The work-around ''echo <string>
> file ;
cat file > /dev/tpm0'' seems to get around this problem.
The patch also removes a redundant test and error output.
