nfit: Account for table size length variation

The size of NFIT tables don't necessarily match the size of the
data structures that we use for them.  For example, the NVDIMM
Control Region Structure table is shorter for a device with
no block control windows than for a device with block control windows.
Other tables, such as Flush Hint Address Structure and the Interleave
Structure are variable length by definition.

Account for the size difference when comparing table entries by
using the actual table size from the table header if it's less
than the structure size.
