src: fix node_crypto.cc compiler warnings

Currently the following compiler warnings are issued by clang:

../src/node_crypto.cc:2801:56:
warning: '&&' within '||' [-Wlogical-op-parentheses]
return tag_len == 4 || tag_len == 8 || tag_len >= 12 && tag_len <= 16;
                                    ~~ ~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~
../src/node_crypto.cc:2801:56:
note: place parentheses around the '&&' expression to silence this
warning
return tag_len == 4 || tag_len == 8 || tag_len >= 12 && tag_len <= 16;
                                                     ^

warning
    if (cipher->auth_tag_len_ != kNoAuthTagLength &&
                                                  ^

This commit adds parenthesis around these expressions to silence the
warnings.
