external/pflash: Perform the correct cleanup
If the -F flag is used then pflash uses a regular file as the flash.
On cleanup pflash fails to tell arch_flash_close() if it had passed a
filename to arch_flash_init() as such arch_flash_close() assumes that
it needs to close the actual flash structure and not simply a file
descriptor leading to a NULL dereference.
