Fix erase and write error code, which should be "protected".

From the "Embedded Peripherals IP User Guide" of Altera,

The "Illegal write" flag indicates that a write instruction is
targeting a protected sector on the flash memory. This bit is
set to indicate that the IP has cancelled a write instruction.

The "Illegal erase" flag indicates that an erase instruction has
been set to a protected sector on the flash memory. This bit is
set to indicate that the IP has cancelled the erase instruction.
