Neel Natu 2b89a04496 Fix a broken assumption in the passthru implementation that the MSI-X table
can only be located at the beginning or the end of the BAR.

If the MSI-table is located in the middle of a BAR then we will split the
BAR into two and create two mappings - one before the table and one after
the table - leaving a hole in place of the table so accesses to it can be
trapped and emulated.
