[PATCH] block-sha1: drop trailing semicolon from macro definition

23119ffb4e (block-sha1: put expanded macro parameters in parentheses,
2012-07-22) added a trailing semicolon to the definition of SHA_MIX
without explanation.  It doesn't matter with the current code, but make
sure to avoid potential surprises by removing it again.

This allows the macro to be used almost like a function: Users can
combine it with operators of their choice, but still must not pass an
expression with side-effects as a parameter, as it would be evaluated
multiple times.

Yes, it was just a typo.
