Pass a correct lowaddr to bus_dma_tag_create(), lnc(4) cards can only

Browse Source 
deal with 24-bit addresses.  While the two other attachments, namely
isa and cbus, do it properly, the PCI attachment was passing
BUS_SPACE_MAXADDR instead of BUS_SPACE_MAXADDR_24BIT.  This bug
became apparent with the new contigmalloc() code.

This fixes the problem reported with lnc(4) interfaces inside VMWare,
and should theoritically also fix any user of a PCI lnc(4) card.  It
is a RELENG_5 MFC candidate.
