fc-fsio: guard against bogus readdir results from the target If the FFS being operated on contains SE K2x0 extended filenames, readdir will return strings that are bad for printing. We need to guard against this possibility, and also against possible other bogosity that could be sent by other alien firmwares.

# This Motorola W220 phone has a single-bank flash chip on nCS0 and
# XRAM on nCS3 instead of the usual nCS1.  The timings are unknown,
# so we set a conservative WS=4.  The flash is 8 MiB, so we need to
# enable ADD22.
