cfi_flash: Fix CONFIG_SYS_FLASH_AUTOPROTECT_LIST usage

Commit 6ee1416e81 (mtd, cfi: introduce
void flash_protect_default(void)) introduced a bug which resulted in
boards that define CONFIG_SYS_FLASH_AUTOPROTECT_LIST not compiling with
the the following errors and warning:
  ptyser@petert u-boot $ make -s xpedite520x
  Configuring for xpedite520x board...
  cfi_flash.c: In function 'flash_protect_default':
  cfi_flash.c:2118: error: 'i' undeclared (first use in this function)
  cfi_flash.c:2118: error: (Each undeclared identifier is reported only once
  cfi_flash.c:2118: error: for each function it appears in.)
  cfi_flash.c:2118: error: 'apl' undeclared (first use in this function)
