LOG: Fix an incorrect bit-width for storing attribute syntax information

This field corresponds to the Syntax enumeration, and that gained
another entry in 1fdf952deeb9a02aa34794af3c1a7d13a30e068e. However,
the bit-field for storing the syntax used was not adjusted to handle
the extra field.

This turns out to be unobservable for HLSL attributes at the moment, so
there is no test coverage. But it's also not really an NFC change
either.
