Loosen up the range test in ndis_register_ioport(). Allow drivers to

map ranges that are smaller than what our resource manager code knows
is available, rather than requiring that they match exactly. This

a range of 32 I/O ports, even though some chips appear set up to
decode a range of 64. With this fix, it loads and runs correctly.
