[PATCH] git-revert: Fix die before git-sh-setup defines it.

The code previously checked it's own name and called 'die' upon
an error.  However 'die' was not yet defined because git-sh-setup
had not been sourced yet.  Instead simply write the error message
to stderr and exit with an error as was originally desired.

I found this by inspection.  I contemplated several different ways of
resolving it but in the end the simplest seemed to be the best.
