arm: stm32f4: fix a bug when a random sector gets erased
Old sector number is not being cleared from FLASH_CR register. For example
when first erased sector was 001 and then you want to erase sector 010,
sector 011 gets erased instead.
This patch clears old sector number from FLASH_CR register before a new
one is written.
