viced: Remove pointless braces

viced: Remove pointless braces

Doing if ((a==b)) is unecessary. It's also potentially dangerous, as
that's the syntax required to do assignment within an if statement.
clang now issues warnings (errors in -Werror mode) when it encounters
these.

Remove pointless braces from viced to make clang happy.
