iwlwifi: move firmware restart debugfs hook to op_mode
This allows to test fw restart flow. The hook in transport
layer doesn't really make the fw assert. Moving this hook
to the op_mode allows to use the fw API to actually send a
host command that will make the fw assert.
Change the restart_fw module parameter to be a boolean on
the way.
