Merge #11594: Improve -disablewallet parameter interaction
7963335 Fix -disablewallet default value (João Barbosa)
b411c2a Improve -disablewallet parameter interaction (João Barbosa)
Pull request description:
The first commit logs a message for each configured wallet if `-disablewallet` is set:
```
bitcoind -printtoconsole -regtest -disablewallet -wallet=foo -wallet=bar
...
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=foo
WalletParameterInteraction: parameter interaction: -disablewallet -> ignoring -wallet=bar
```
It also moves up the `-disablewallet` check which avoids the unnecessary `-wallet` soft set.
The second commit fixes the default value of `-disablewallet`, currently the value is correct, but it should use `DEFAULT_DISABLE_WALLET`.
The third commit can be dropped or squashed, just took the opportunity to fix the coding style there.
