Add styling to password field validation message during create user

[Nikunj Aggarwal]

While creating or editing a user in the Users panel, if user enters the different "Confirm Password" then it shows a message saying "Passwords do not match.".

But it should show this message with a error background.

Also the eye icon moves at the top from the input box and aligns with error message.
