Merge bitcoin#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.
