Kinetis: suppress false alarms "MCU is secured"

Kinetis driver checks MDM STAT register to detect secured state of MCU.
An unsecured clean device typically triggered a huge fat alarm message.
Now when driver detects secured state it tries to halt MCU and then
re-reads status register.

Command "mdm mass_erase" used to deassert reset when finished
and MCU started looping in hard fault - WDOG reset cycle.
Now "reset halt" is issued. Clean flash is not run after mass_erase.
