arm: imx: hab: Make authenticate_image() return zero on open boards

Browse source 
The BootROM will not successfully process a HAB image passed by u-boot
unless the board has been set into locked mode. Some of the existing usages
of authenticate_image() expect and rely on unlocked boards doing the
following

1. Not calling into the BootROM authenticate_image() callback
2. Returning a pass status for authenticate_image() calls anyway

A previous patch removed the necessity to call into imx_hab_is_enabled()
twice. This patch ensures the reliance on authenticate_image() returning
zero is maintained.
