stm32f4: Fixes erase_mass command return error. 

The final erase_mass command check is looking for the EOP (End of
OPeration) bit to be set. This bit is only set when the EOP interrupts
(EOPIE = 1) are enabled. We are not enabling those on the target so this
bit will never get set. As we are monitoring the BSY flag to make sure
the erase_mass operation is still ongoing and finished it is enough if
we just check the error flags.
