[PATCH kernel v2] panic: Dump registers on panic_on_warn

[Alexey Kardashevskiy]

Currently we print stack and registers for ordinary warnings but
we do not for panic_on_warn which looks as oversight - panic()
will reboot the machine but won't print registers.

This moves printing of registers and modules earlier.

This does not move the stack dumping as panic() dumps it.
