truncation from 'int' to bit-field changes value from 3 to 1 [-Werror,-Wbitfield-constant-conversion]

[xuguangxin]

step to reproduce.

1. apply this commit fix build for clang #12
2. build with CFLAGS="-Werror -Wbitfield-constant-conversion" CXXFLAGS="-Werror -Wbitfield-constant-conversion" cmake .. -DCMAKE_C_COMPILER=clang -DCMAKE_CXX_COMPILER=clang++"

you will see errors like this:

The WT is 1 bits variable but the code assign 3 to it

please conside fix it.thanks
