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.
