    stm32lx: do not attempt mass-erase in-place of first bank erase
    
    Commit 832f0a5bfb439ed9b6e16df69c4dd95e001db015 'stm32: add mass erase support for STM32L' added
    use of mass-erase in-place of bank-erase. This is triggered if first bank is requested to be
    fully erased.
    
    This erroneous action completely fails on STM32L162VEY (512 KiB flash in two banks) and also
    unintently destroying contents of EEPROM and second flash bank.
